Grandma's Meatloaf

My grandma made this for dinner for us all on Sunday after Conference was over and although I wasn't super excited about meatloaf going into dinner, it was actually delicious! She said it was either her mom or her grandma's recipe too, so I figured I better document this family recipe! It sounds easy enough...

Ingredients:
1 1/2 lb. lean ground beef
3/4 c. oatmeal
1/4 c. chopped onion
1 1/2 t. garlic salt
pepper
1 egg, beaten
3/4 c. milk
Sauce:
1/2 c. ketchup
2 T. brown sugar
1 T. yellow mustard
sliced bacon, optional

Directions:
Mix and squish together all ingredients and form into your loaf pan.
Mix all the sauce ingredients, except bacon, and pour on top of loaf. She likes to make extra sauce (1 1/2 to 2 times the recipe).
Place sliced of uncooked bacon over the very top (this was a great addition in my opinion!).
Bake at 350 degrees for 1 hour.
We had some extra barbecue sauce on the table for ours and it was served with mashed potatoes, green salad and sourdough bread.
