Preheat oven to 350 F degrees. Spray a 9×13 or 3 quart baking dish with nonstick spray and set aside.
Heat a large, deep skillet over medium high heat and add olive oil. Add ground beef and cook, crumbling with a wooden spoon or potato masher, until browned and mostly cooked, about 4-5 minutes.
Add onion and jalapeno to beef. Cook, stirring often, until softened and fragrant, about 4 minutes. Add garlic and cook about 1 minute. Beef should be fully cooked and brown at this point.
Drain any fat and return to skillet. Stir in taco seasoning, black beans, green chiles, salt, pepper, tomato paste and picante sauce. Cook 1-2 minutes.
Set skillet aside and add 1 1/2 cups of shredded cheese.
Transfer beef mixture to prepared baking dish and top with remaining 1 1/2 cups of cheese.
Bake approximately 25 minutes, until hot and bubbly and cheese is melted. Top with desired toppings and serve!
