Best Ever Meatloaf

2 eggs
2/3 c. milk
3 slices bread
1/2 c. chopped onion
4 oz. shredded cheese
1 tsp. salt
1/4 tsp. black pepper
1 1/2 lbs. lean ground beef

Topping: 1/2 c. tomato sauce
1/2 c. brown sugar
1 tsp. mustard

Beat eggs. Add milk and bread and let stand until bread absorbs liquid. Stir in onion and cheese. Add ground beef. Mix well. Shape into loaf.

Bake at 350 degrees for 45 min. (I have also put this in my crockpot and cooked on high for a couple of hours.) Combine topping and spoon over meatloaf after about 30 minutes. Spoon topping over mixture every 10 minutes until done. (When doing this in the crockpot, I just spoon over topping about 20 min. before serving time and again about 10 min. later.)
