- Prepare outdoor grill for direct grilling over medium-high heat. Prepare rice as label directs; cool slightly.
- In food processor, process rice, beans, breadcrumbs, walnuts, steak seasoning, pepper and garlic powder 2 minutes or until a thick dough forms but some small pieces remain, scraping down bowl occasionally; form into 4 (1/2-inch-thick) patties.
