  • 2 tablespoons whole grain mustard
  • 1 tablespoon Dijon mustard
  • 1 tablespoon red wine vinegar
  • 2 teaspoons soy sauce
  • 4 cloves garlic, minced
  • 1 teaspoon dried rosemary
  • 1 teaspoon paprika
  • 1/4 teaspoon salt
  • 1/4 teaspoon pepper
  • 1 1/2 lbs top sirloin roast or steaks (see note)


  1. Add all of the marinade ingredients to a large bowl and stir to combine. Add the steaks and marinade 15 minutes or longer.
  2. While meat is marinating, preheat grill to medium-high heat and oil the grate.
  3. Grill steaks for 4-5 minutes per side or until desired doneness (medium = 160 degrees and  medium rare =145 degrees).

Recipe Notes
It's less expensive to buy a big roast and cut into your own steaks.
