Not sure why these are called Wimpy burgers. Wimpy was a Popeye cartoon character.
He was very intelligent and well educated but a big lazy moocher as well. His famous line, "I'll gladly pay you Tuesday for a hamburger today." is what he is know for.
Well you could make the burgers one day and then simmer them the next in the sauce. o could put them in a slow cooker in the morning and come home and put them on some French rolls. These were a little salty for me. I eat a lot sodium diet so for others it may be just right. I will try with a reduced sodium broth next time.
6 hamburgers patties pre-cooked
3 cups beef broth
2 onions, sliced thickly
1/4 cup ketchup
Mix the broth, onions and ketchup together. Add the hamburgers patties. Cook on low heat for at least 20 minutes. If using roll cut in half and place into roll.
