Heat up your electric skillet to the setting right above warm.
Add 2 tablespoons of oil, the onions, and a pinch of kosher salt. Slowly cook until the onions have soften and taken on brown color about a half hour, flipping the onions every so often.
Add 1 tablespoon of oil, the peppers, and a pinch of kosher salt. Increase the heat to 300 degrees or medium and cook until the peppers have soften about 5-10 minutes.
Use chicken broth or water and scrap the brown stuff off the bottom of the pan. Add in chicken and the cumin. Cook until the chicken is warmed through about 2-4 minutes.
Reduce the heat to warm. Serve with tortillas, cream, cilantro, and cheese.
