In a skillet over medium heat, brown the ground beef or turkey with diced onion and minced garlic until fully cooked. Drain any excess fat.

Transfer the cooked meat mixture to the slow cooker.

Add the black beans, corn, diced tomatoes, frozen mixed vegetables, chili powder, cumin, smoked paprika, salt, and pepper to the slow cooker. Stir well to combine.

Cover and cook on low for 4 to 6 hours, or until heated through and flavors have melded.

About 30 minutes before serving, sprinkle the shredded cheddar cheese on top and layer the tater tots over the cheese.

Cover and cook for an additional 30 minutes, until the tater tots are crispy and the cheese is melted.

Serve hot and enjoy your hearty cowboy casserole!
