Step 1

Adjust oven rack to lower-middle position and preheat oven to 375°F.

Step 2

Heat oil over medium-high heat in a large sauté pan. When oil is shimmering, cook chicken, breaking into bits until no longer pink and lightly browned, about 7 minutes total. Reduce heat to medium and add onion and garlic. Sauté for 3 minutes. Stir in tomatoes, salsa, cumin, onion and cocoa powders and Worcestershire sauce and brig to a boil, scraping any browned bits from the bottom of the pot. Season with salt and pepper.

Step 3

Meanwhile, brown chorizo over medium-high heat in a medium-sized sauté pan, breaking into bits until cooked through, 5 to 7 minutes. Drain grease from pan and discard. Add serrano peppers and sauté for 3 more minutes, until beginning to soften. Add pinto and refried beans. Stir to combine and gently mash bean mixture, leaving some texture. Season with salt and pepper.

Step 4

Spray cooking spray on the bottom and sides of a 13” x 9” baking dish. Spread a few spoonfuls of the tomato sauce on the bottom of the pan, to coat. Top with a layer of flour tortillas, overlapping and cutting as needed to form a fully covered bottom layer. Spread 1/2 of bean mixture on top, followed by several spoonfuls of the tomato sauce. Top evenly with half of corn, followed by 1/3 of each of the cheeses. Repeat layer, starting with tortillas. After layer this is complete, top with another layer of tortillas. Spread this final tortilla layer with additional tomato sauce and the remaining 1/3 cheese. Scatter sliced jalapenos and red onion on top.

Step 5

Place in oven and bake until browned and bubbly, 30-35 minutes. Remove from oven and let cool for 10 minutes before cutting and serving with sour cream and limes.
