Vegetarian Cheesy Mexican-style Lasagna Casserole with corn tortillas, poblanos, and bell pepper
Place flour, ½ teaspoon salt, and black pepper in a large saucepan. Gradually add milk and broth, stirring with a whisk. Cook over medium heat until slightly thick (about 12 minutes), stirring constantly. Remove from heat. Combine milk mixture and poblanos in a blender; process until smooth. Stir pureed poblano mixture into remaining milk mixture.
Coat bottom of a 13 x 9-inch baking dish with oil or cooking spray. Spread ½ cup sauce in bottom of dish. Arrange 6 tortillas over sauce, overlapping slightly. Spread half of ricotta mixture over tortillas; top with half of white beans. Sprinkle with 1/3 cup green onions and 2/3 cup cheese. Pour about 1 cup sauce over cheese. Repeat layers with 6 tortillas, remaining ricotta mixture, remaining beans, 1/3 cup green onions, 1 cup sauce, and 6 tortillas. Pour remaining sauce over tortillas. Coat 1 side of foil with oil or cooking spray. Place foil, coated side down, over casserole. Bake at 350° F for 30 minutes or until bubbly.
Uncover; sprinkle with remaining cheese. Bake, uncovered, 15 minutes or until cheese melts. Let stand 15 minutes. Garnish with remaining green onions, sliced avocado, and hot sauce as desired. Enjoy!
