💡 Pro Tips Section
- Storage: Keep leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven until warmed through.
- Substitutions: If you are out of bell peppers, zucchini slices make a great, mild alternative that roasts beautifully.
- Prevent Sogginess: If your peppers release too much water, pat them dry after washing and ensure you do not crowd the baking dish too heavily.
Variations
- Low-Carb Version: Serve over cauliflower rice instead of flour tortillas.
- Extra Heat: Add one finely diced jalapeño to the mix before baking for an extra kick of spice.
FAQ
- Can I use frozen chicken? It is best to thaw the chicken completely before baking to ensure even cooking and prevent excess water in the dish.
- Can I make this ahead of time? Yes! You can slice the chicken and veggies the night before. Keep them in the fridge and add the oil/spices right before you are ready to bake.
