He went to the store and found Tri-tip and then had the butcher grind it 2 times. Yup steak. A bit on the expensive side. The measurements are done guy style meaning, I'm going to do the best I can telling you how much to use.
4 lbs Ground Tri-tip
1/2 yellow onion - chopped
1/2 green bell pepper - Chopped
1/2 red bell pepper - chopped
12 Slices mushrooms
He sprinkled any left over veggies or what had fallen onto the pan over the top of the patties. And sprinkled with spices. Then he barbecued. Right before they were done he placed a slice of mild cheddar and a slice of provolone cheese on each. He used bakery fresh buns, served them with corn and a salad.
I'm not even going to try to do the calorie count on these. Just plan for that to be your only meal if you're counting. They were well worth it!
