Clean and chop the tomatoes and add them to the blender. Also add in the blender, the chipotle peppers, 1 of the garlic cloves, the oregano, the broth and/or juice and salt and pepper to taste. Blend until smooth.
Slice your garlic cloves and heat a large frying pan over medium heat with a little oil to saute.
Add in the onions and cook until about translucent, 4-5 minutes. Add the garlic and cook until fragrant, about 1 more minute.
Turn the heat down slightly and add in the sauce. Cook for about 5 minutes to heat through and it will begin to reduce.Turn the heat to low and add in the chicken.
Stir to completely cover the chicken in the sauce and simmer for about 15-20 minutes. Check seasoning and adjust if needed. Serve immediately with tortillas for taco, tostadas or make into nachos! ENJOY!!
