1 lb sirloin tips
2 T. Extra virgin olive oil
2 T. tamari
2 cloves garlic, minced
2 T. Lemon juice
1 T. Dijon mustard

Mix together marinade ingredients. In a non-reactive container just large enough to hold the meat, mix marinade and beef, coating beef well with marinade. Allow to marinate 6–8 hours, or overnight, in refrigerator. Bring to room temperature before cooking. Prepare fire or grill, or turn on broiler. When fire is medium hot, remove sirloin tips from marinade. Grill the first side for 30 seconds, turn, grill second side for 30 seconds and return to first side. Cook 5 minutes or until done. Remove from grill, allow to rest 5–10 minutes before slicing. If using in sandwiches, serve with horseradish sauce or hot and sweet mustards. If grilling as kebabs, grill with tomatoes, mushrooms and green pepper sections, water chestnuts, snow peas and red pepper sections.
