Sweet and Sour Meatloaf

My sister was visiting recently and  told me that this recipe was our Aunt Claudeens'. Claudeen is such a wonderful cook and I know our Mother used many of her recipes. Our Mother has passed away, this past January. We miss her dearly. I made this meatloaf recently for my daughter that was expecting her second baby. Grace Ann has since been born, she is beautiful and healthy and I'm so happy that I will be able to share these family recipes with her and her brother.

Sweet and Sour Meatloaf

1 8 oz can of tomato sauce
1/4 cup brown sugar(Mother's note says to use more)
1/4 cup vinegar
1 tsp prepared mustard
1 egg
1 small onion
1/4 cup crushed crackers(we always use saltines)
2 lbs ground chuck
1 1/2 tsp salt
1/4 tsp pepper

Mix tomato sauce, mustard, sugar, vinegar.

Mix the rest of the ingredients like normal meatloaf. Mix in 1/2 of the sauce.

 Form and put in loaf pan or on baking sheet. Top with the rest of the sauce.

Bake 400 degrees for 45 minutes.
