Step 1Slice roll parallel to work surface, being careful not to cut all the way through. In a large cast-iron skillet over medium heat, melt 1 tablespoon butter. Toast roll cut sides down, rotating occasionally, until browned in places, 3 to 4 minutes. Transfer roll to a plate.

Step 2In same skillet over medium-high heat, melt remaining 1 tablespoon butter. Form meat into a ball shape; season with salt and pepper. Using your hand or a spatula, press meat down into skillet to flatten. Cook, undisturbed, until bottom is browned, 3 to 5 minutes. Turn meat, then add onions. Cook, breaking up meat into small pieces, until just browned and onion is translucent, about 3 minutes more.

Step 3Arrange cheese slices over beef mixture. Remove from heat, cover skillet, and let melt.

Step 4Spread cut sides of roll with mayonnaise, then ketchup. Scoop meat mixture onto one side of roll. Top with lettuce and tomatoes. Close roll as best as you can, then cut in half.
