• Heat the olive oil in a large-skillet over medium-high-heat for2 minutes. Then add onions and beef.
• Cook, stirring to break up the beef, till the beef is browned and the onion is tender for 5 minutes. When there are fluids in the bottom of the skillet, then drain the mix and then return it to the skillet.
• Stir in the black pepper, garlic and kosher salt. Cook, stirring for a few minute.
• Turn off the heat. Stir in the unsweetened ketchup, mayonnaise, mustard and 1 cup cheddar.

• Bake until the cheese is melted and the casserole is heated through, for 15 minutes.
• Or, if your baking-dish is broiler-safe, broil the casserole 6-inches below the heating element (not straight under ) till cheese is melted, for 1-2 minutes.
