In a large, non-stick skillet brown the ground sirloin over medium-high heat. Add the Manwich sauce and simmer for about 5 minutes. Remove from heat.

Spread sourdough bread on one side with butter. On the unbuttered sides place a couple of slices of Provolone cheese and about 1/4 cup Manwich per sandwich.

Grill the sandwiches and serve with dill pickles.
