1 tablespoon olive oil
3 tablespoons unsalted butter
2 pounds lean ground beef
3 cloves garlic, minced
1 1/2 teaspoons dried onion
1 pound florets
1/4 cup ketchup
2 teaspoons sugar
3 tablespoons prepared horseradish
In a large metal bowl, warm olive oil over medium heat. Roll meat into small strips, then cut each strip into 1/4 inch strips.
Heat the butter and sugar in a large skillet over medium heat. Fry the ground beef strips until browned. Drain grease from skillet, scraping pan and discarding water.
Place meat strips in the skillet. Fry for 2 minutes per side, or until browned. Drain excess fat, then stir in mustard and ketchup. Cook over medium-low heat, stirring constantly, until beef strips are browned.
