Adjust cayenne to your preferred spiciness level. I've found that 1 teaspoon is enough to provide consistent (and building) heat. I'd suggest using closer to ½ teaspoon (or less) if you are sensitive to spicy foods.
To make this recipe vegetarian, you could use sliced mushrooms instead of the chicken breast. Additionally, I might suggest using the full onion and adding an extra bell pepper.
My favorite toppings include:
- shredded cheese (
Cabot to keep it lactose-free)
- salsa
- guacamole
- sour cream (
Kite Hill or
Tofutti to keep it DF)
- diced red onion
- sliced avocado
- fresh cilantro
- scallions
- fresh lime juice
