Step 1: Preheat the oven to 350°F (175°C) to ensure even cooking.
Step 2: In a large skillet over medium heat, cook the ground beef with salt, pepper, garlic powder, cumin, and chili powder until browned.
Step 3: Stir in the tomato sauce and salsa, followed by the drained Great Northern beans. Mix until well combined and heated through.
