Step number one. In a large skillet brown ground beef, bacon, onion and garlic over medium heat until beef is no longer pink. Sprinkle the flour over the ground beef and stir well to combine. Stir in the milk, Worcestershire sauce and hot sauce. Cook for 2-3 minutes or until thickened. Remove from heat and stir in the cheddar, frozen vegetables and sour cream.
And now, Spray the crock pot with non-stick spray. Place some tater tots in the bottom of the crock pot. Pour meat gravy over tater tots. Arrange remaining tater tots on top. Cover and cook on LOW for 3-3 1/2 hours. In the last 10 minutes of cooking sprinkle with extra cheddar if desired. Cover and finish cooking.
