High Protein Meal Prep: Chicken Fajita Cauliflower Bowls

• A sheet pan handles the chicken, peppers, and onion at the same oven temperature. That keeps active prep focused on slicing vegetables, stirring sauce, and portioning containers rather than managing several burners.
• Cauliflower rice creates a roomy bowl base without relying on low-carb bread or a complicated specialty ingredient. Black beans bring a softer, more substantial component, while the peppers retain enough texture to separate each bite.
• The lime yogurt sauce is packed separately instead of roasted with the vegetables. That decision preserves its tang and lets you control moisture when reheating, which matters when these bowls sit assembled for several days.

• 1 1/2 lb boneless, skinless chicken breasts, cut into strips (680 g)
• 2 medium bell peppers, thinly sliced (300 g)
• 1 large red onion, thinly sliced (200 g)
• 4 cups cauliflower rice, fresh or frozen (500 g)
• 1 1/2 cups canned black beans, drained and rinsed (255 g)
• 1/2 cup plain Greek yogurt (120 g)
• 2 tablespoons lime juice (30 g)
• 2 tablespoons olive oil (27 g)
• 2 tablespoons fajita seasoning (18 g)
• 2 tablespoons chopped cilantro (8 g)

Ingredient notes

• Chicken breasts are lean, quick to slice, and easy to distribute evenly across four containers. Cut similarly sized strips so they finish together, and leave space between pieces on the pan for better browning rather than steaming.
• Use any combination of red, yellow, orange, or green bell peppers. Red and yellow peppers bring more sweetness, while green peppers taste sharper; the trade-off is flavor direction, not a better or worse bowl.
• Fresh cauliflower rice roasts quickly, while frozen cauliflower rice may release more moisture. Use it straight from frozen and spread it widely; the trade-off is convenience versus a slightly drier, more separated texture after roasting.
• Canned black beans add color and a creamy contrast to the roasted ingredients. Drain and rinse them well before adding, then warm them briefly rather than roasting them from the start, which helps prevent their skins from drying out.
• Plain Greek yogurt provides the base for the lime sauce and carries the fajita seasoning well. Choose a texture you enjoy eating cold; a thicker yogurt makes a more spoonable sauce, while a looser one spreads easily through warm vegetables.

1. 1Heat the oven

   Set the oven to 425°F and position one rack in the upper middle. Line a large rimmed sheet pan with parchment or use two pans if the ingredients will be crowded. Crowding traps moisture, so give the chicken and vegetables room to roast instead of pile them in the center.

2. 2Season the chicken

   Place the chicken strips in a bowl with half the olive oil and half the fajita seasoning. Toss until each strip is coated, then arrange the chicken on one side of the prepared pan. Keep the strips in a mostly single layer so their edges can color evenly.

   

3. 3Add the vegetables

   Toss the peppers and onion with the remaining olive oil and seasoning. Spread them across the open side of the pan, keeping the chicken separate for easy portioning later. Roast for 12 minutes, then use tongs to turn the chicken and stir the vegetables.

4. 4Roast the cauliflower rice

   Add the cauliflower rice to a second lined pan or a clear section of the first pan. Spread it into a thin layer and return both pans to the oven. Roast until the chicken reaches 165°F in the center and the vegetables have browned edges, about 8 to 12 minutes more.

   

5. 5Stir the sauce

   While the pans finish, stir yogurt, lime juice, and cilantro in a small bowl. Taste and add a small pinch of salt if needed. Warm the drained beans in a microwave bowl or small saucepan just until heated through, then keep them separate from the sauce.

6. 6Build the containers

   Let the roasted components cool briefly, then divide cauliflower rice, chicken, peppers, onion, and beans among four containers. Spoon the lime yogurt sauce into small lidded cups or place it in one corner. Seal the bowls once the components are no longer steaming heavily.

• Use two sheet pans when the ingredients cannot sit in a single layer. A crowded pan gives the vegetables a softer finish and makes the chicken release more liquid, which can leave the cauliflower rice wet.
• Slice the chicken against the grain into strips of similar thickness. Thin pieces cook rapidly, so check the center of the largest strip with a thermometer instead of judging the entire batch by one small piece.
• Keep the sauce in separate cups if you prefer a drier cauliflower rice base after reheating. Stir it through immediately before eating for a creamy finish without letting it soak into the vegetables.
• For cleaner portions, divide the cauliflower rice first, then add chicken, peppers, beans, and sauce. That fixed order makes it easier to notice if one container is noticeably lighter than the others.

Serve one bowl hot with the cold lime yogurt sauce added at the table. A wedge of lime, sliced avocado, chopped cilantro, or pickled jalapeños can add contrast without changing the batch method. For dinner, pair the bowl with a crisp cabbage salad dressed with lime and olive oil. If you want more vegetables, add shredded lettuce after reheating so it stays cool and crunchy beside the warm chicken and peppers.
