Heat oil in a deep skillet or saucepan over medium-high heat. Once hot add onion and garlic. Cook until onion is translucent. Add in oregano and cumin. Cook, stirring constantly, for 30 seconds.
2 tablespoon olive oil, 1 medium onion, 4 cloves garlic, 4 teaspoon dried oregano, 1 teaspoon ground cumin
Add in chipotles in adobo, fire roasted tomatoes, chicken broth and salt. Bring to a simmer. Using an immersion blender (or regular blender/food processor) carefully blend ingredients until mostly smooth. This is a personal preference so go as smooth as you like. If using a blender or food processor add the sauce back into the skillet.
2-4 chipotle peppers in adobo, 2 14.5 oz cans fire roasted tomatoes, ½ cup chicken broth, 1 teaspoon kosher salt
Add in shredded chicken and stir to coat in sauce. Allow to warm through.
6 cups rotisserie chicken meat
