This is from The Son of Grok's great website. I adapted it to our family size and preferences.
Sauce:
6 oz tomato paste
1 ½ teaspoon garlic salt
1 small green bell pepper, finely diced
3 lb ground beef
½ of a green bell pepper finely diced
½ of a red bell pepper finely diced
½ of an onion finely diced
3 eggs
6 oz tomato paste
12 slices of bacon chopped
1 Tbsp garlic salt
1 Tbsp black pepper
1 Tbsp salt
Chunks of Swiss or cheddar cheese to mix throughout (optional)
Preheat oven to 375. Mix all the "loaf" ingredients in a bowl. Form into desired loaf shape. I like to make hamburger patties and cook them on a grill.
Mix all the sauce ingredients. Spread sauce on top of loaves. Bake loaves 45-60 minutes. When done, add more sauce and serve.
