- 12 oz cremini mushrooms.
- 3 garlic gloves, sliced thinly.

Steak directions:

- Grill over direct heat for 4 minutes, then rotate the meat 90 degrees and cook 2 more minutes. Repeat on the other side.
- Move the steak to the cooler part of the grill and position the smaller end away from the heat.
- Cover and cook until the meat reaches 125 to 130 degrees Fahrenheit on a food thermometer for medium-rare, 12 to 15 minutes.
- Let rest 5 minutes before slicing.
- While the steak is cooking, heat 2 tbsp of butter in a large nonstick pan.
- Once the butter is melted, add the mushrooms in a single layer. Cook for 5 to 7 minutes to caramelize the mushrooms.
