Crumble the ground beef into a large skillet over medium-high heat. Cook and stir until evenly browned, crumbling even more as it cooks. Drain off the grease. Stir in the onion soup mix and French onion soup. Cover, and simmer over low heat for about 2 hours, or you may transfer to a slow cooker for this part.
To serve, spoon onto hamburger buns like a sloppy Joe.
