Shotgun Willie's Sirloin Steak for Two

1 pound sirloin steak, about 3/4 inch thick
1 tablespoon (or more) Shotgun Willie's Rowdy Rub (recipe follows)
6 button mushrooms
2 slices of onion, thick sliced
Your favorite Italian dressing

Rub the steak with Shotgun Willie's Rowdy Rub about 20 minutes before grilling and allow steak to sit at room temperature. Put the mushrooms and onion slices on a plate and drizzle a couple tablespoon of dressing over them. Place all on the grill for about 8 minutes until steak is cooked to desired doneness. Put the onion slices and mushrooms on top of the steak and allow to rest a minute or two. Cut the steak in half and serve.

Shotgun Willie's Rowdy Rub:
1 tablespoon chili powder
1 tablespoon paprika
1 tablespoon ground cumin
1 tablespoon dried marjoram
1 tablespoon dry mustard
1-1/2 tablespoon fresh cracked peppercorns

Place all in a spice grinder and pulse a few times to blend thoroughly. Store like all spices, in a tightly sealed jar away from heat and light.
