Old-Fashioned, Traditional Meatloaf - cooking recipe

Ingredients

1 1/2 lbs ground beef (I use lean)
1 medium onion, chopped
5 slices bread, broken up
1 egg, beaten
2 -3 tablespoons ketchup
1 tablespoon brown mustard
1/2 teaspoon black pepper
1 -2 tablespoon milk, as needed

Preparation

Preheat oven to 350 degrees.
In a large bowl, combine all ingredients and mix well (use your hands for best results).
Transfer meat into a 9\"x13\" baking pan.
Shape into a loaf - it should be fairly moist and slightly \"sticky\" to the touch. If it's too wet, add bread (or dry crumbs) to improve consistency.
Do not cover.
Bake at 350 degrees for 55 min, or until done.
