Adapted slightly from Gimme Some Oven
2 Tbsp. extra virgin olive oil
1 medium white or yellow onion, diced
2 poblano peppers, seeded and stemmed, diced
1 jalapeno pepper, seeded and stemmed, diced
8-10 (I had a little filling left) whole wheat enchiladas
4 cups shredded cooked chicken (or turkey)
2-3 cups Shredded Monterey Jack cheese, divided
Avocado Cream Sauce:
2 Tbsp. butter
2 Tbsp. flour
2 cups low-sodium chicken broth (or stock)
3/4 cup plain Greek yogurt
1/2 tsp. cumin
1/2 tsp. salt
1/2 tsp. garlic powder
1/4 tsp. pepper
2 avocados, peeled and pitted
1/2 cup fresh cilantro
juice of 1 lime
For the avocado cream sauce, melt the butter in a skillet over medium high heat. Add flour, whisking until golden brown and bubbly, about 2-3 minutes. Slowly whisk the broth into the flour mixture. Bring to a boil, then reduce heat to medium-low and simmer for 5 minutes. Stir in the Greek yogurt, cumin, salt, garlic powder, and pepper. Whisk as necessary to remove any lumps. Remove from the heat and transfer the mixture to a heat-safe bowl. Add avocado, cilantro, and lime juice. Blend using an immersion blender until smooth. Alternately, you can let the mixture cool slightly and then blend in a traditional blender.
Preheat the oven to 375 degrees and grease a 9x13 inch pan. In another skillet, heat the olive oil over medium heat. Add the onion, poblano, and jalapeno, and saute for 5-6 minutes until the onions become translucent. Remove from heat. Mix in the shredded chicken.
Spread a little avocado sauce over the bottom of the prepared pan. To assemble the enchiladas, place a tortilla on a flat surface. Spread some avocado sauce on the top 1/3 of the tortilla. Top with the chicken mixture and shredded cheese. Repeat until the pan is full or you have used all the filling. Spread the remaining avocado sauce over the top of the enchiladas. Top with remaining shredded cheese. Spray a piece of foil with nonstick spray and cover the pan with the spray-side down. Bake for 20 minutes or until the dish is heated through and the tortillas being to harden. Serve and enjoy.
