Preheat the oven to 375ºF. Heat oil in a large pan over medium heat. Add onion, pepper, and garlic, and cook for about 10 minutes, until onion and peppers are soft. Stir in spices and cook for another minute or two. Add Beyond Beef (or lentils) and break it up with a fork until it's crumbly. Cook for about 10 minutes, until it's no longer pink. Add the refried beans and tomato sauce. Stir to combine and cook until everything is heated through and the flavors have come together about 10 more minutes. Arrange the tortilla chips in a 12-inch cast-iron skillet. Alternatively, lay parchment paper on a baking tray and arrange chips on the tray. Spoon the bean mixture over the chips–it should be thick. Sprinkle cheese and olives on top. Bake in the oven for about 15 minutes, until the cheese has fully melted. Remove the skillet from the oven and arrange your favorite toppings over the cheese. Squeeze fresh lime juice and serve by placing the skillet on a cutting board or trivet and letting people dig in with their forks. For a more civilized approach, let people use a fork or spatula to serve themselves on small plates!
