Chicken Tinga Tostada

• Buy crispy Corn Tortillas
• Kosher salt
• Prepared rotisserie chicken, skin and bones discarded, meat shredded
• 2 tablespoons olive oil 
• 1 cup yellow onion, 1/8 inch diced
• 2 garlic cloves, minced
• 1 teaspoon cumin
• ¼ teaspoon oregano
• 14 ounces fire roasted crushed tomatoes
• ¼ can chipotles (chilies and adobo) (You can also use roasted poblano peppers)
• 1 cup chicken stock

Set aside the shredded rotisserie chicken until ready to use. Meanwhile prepare the sauce. 

Heat the olive oil over medium heat in a heavy-bottomed pot.  Add the onion and garlic and cumin and cook until the aromatics are soft, 4-5 minutes. Add the remaining ingredients and cook on low for 15-20 minutes. Carefully transfer the sauce to a blender and puree until smooth. Return the sauce to the same pan and continue to cook, stirring often, until slightly reduced and thickened, about 5 minutes.   Add the meat, warm through and taste for seasoning. 

Garnish

• Sea salt
• Cotija cheese, crumbled
• Cilantro, chiffonade 
• Sour cream, if desired
• Lime wedges 

To serve, top each tostada with a generous scoop of chicken tinga, season with a sprinkle of sea salt, cotija cheese, cilantro and dots of sour cream, if desired. Serve with a lime wedge on the side.
