Heat a large skillet over medium-high. Brown the chorizo for 2-3 minutes, then add the chicken until warmed through. Remove the chorizo and chicken, and set aside.
Add the onions to the skillet and sauté for 1 minute. Add the zucchini, red pepper, and a tablespoon of oil if needed. Sauté for 2-3 minutes, until just cooked, but not mushy. Salt and pepper to taste. Then add the protein back in.
Remove from heat and stir in the cilantro. Serve immediately.
Notes
NOTE: This is a GREAT recipe to make use of leftover chicken or a store-bought rotisserie chicken.
