Preheat the oven to 350 degrees F.
In a large bowl, mix together the beef, cheese, onion, green pepper, bread crumbs, salt, thyme, and garlic salt. Combine the eggs and tomato puree and blend into the meat mixture. Turn into two 8-inch by 4-inch loaf pans. Bake for 1 hour.
A favorite every time! If you’re not feeding a crowd, freeze one loaf (either before or after baking) for later use.
