Mom's Best Meat Loaf

1 ½ pound ground beef

¾ cups rolled oats

¼ cup chopped onion

1 ½ teaspoon salt

¼ cup pepper

¾ cup milk

Combine all ingredients and mix thoroughly. 

Pack firmly into loaf pan.

Combine ingredients for sauce.

1/3 cup catsup

2 tablespoons brown sugar

1 tablespoon mustard

I double the sauce because my husband and father really like more sauce on it, I usually will put in minced onion too if I don't have onions, and only 1/8 cup.

Pour over meatloaf and bake at 350* for 1 hour.
