Ingredients 1 tablespoon olive oil 1 large onion, finely chopped 2 garlic cloves, minced Coarse salt and ground pepper ¾ pound ground beef sirloin 1 can (14 ½ ounces) tomato puree ½ teaspoon mustard powder 1 ½ teaspoons dark-brown sugar 1 tablespoon cider vinegar 16 party-size potato rolls Directions Heat oil over medium in a large saucepan. Add onion and garlic; season with salt and pepper. Cook until softened, stirring occasionally, 6 to 8 minutes. Add beef, and cook, breaking up meat with a wooden spoon, until no longer pink, 4 to 5 minutes. Add tomato puree, mustard powder, sugar, and vinegar. Cook, stirring occasionally, until slightly thickened, 8 to 10 minutes. (To store, refrigerate, up to 2 days.) Serve warm on rolls. Cook's Notes With leaner ground sirloin, the sliders have less fat and the rolls won't get soggy. Print
