Heat oven to 350°F and spray a 7x11-inch baking dish with cooking spray.
Heat a large skillet over medium heat, and add the olive oil and butter. Add the chopped onion and cook 3-4 minutes or until translucent and tender. Add the minced garlic, stir and cook 30 seconds until the garlic has blossomed and is fragrant. Transfer the onion and garlic to a paper towel-lined plate; set aside.
1 tbsp olive oil, 1 tbsp unsalted butter, 1 medium yellow onion, 2 cloves garlic
Place the ground chuck in the skillet and cook until browned. Drain the fat from the beef in a mesh colander and return the beef to the skillet. Add the onion/garlic mixture, salt, pepper, taco seasoning, Worcestershire Sauce, cider vinegar, tomato sauce and diced tomatoes.
1 lb. ground chuck, 1 packet taco seasoning, 1 tsp Worcestershire Sauce, 2 tsp apple cider vinegar, 1 can tomato sauce, 1 can petite diced tomatoes
Mix well and bring the mixture to a low boil over medium heat.
Reduce the heat to low and add the beans, mix well. Simmer, stirring often, for 15-20 minutes or until the mixture has thickened and most of the liquid has evaporated. Season to taste, with kosher salt and freshly ground black pepper. Keep in mind, Fritos are very salty and so is cheese, so use salt lightly.
¼ tsp ground black pepper, 1 can black beans, drained, kosher salt
Place 2 cups corn chips in an even layer on the bottom of the prepared casserole dish. Top with 1 cup shredded cheese, taco meat, 1 cup cheese, and another 2 cups corn chips.
1 bag Fritos Corn Chips, 2-3 cups Mexican-style shredded cheese
Bake 15-20 minutes or until the casserole is heated throughout.
Serve with chopped tomatoes, lettuce, black olives, chopped scallions, chopped cilantro and/or your other favorite taco toppings. Enjoy!
