Two Sundays ago (Apr 3), I grilled a nice ribeye. Along with sliced Japanese sweet potato and mushrooms. (to be perfectly clear, all grilled). The mushrooms are large portabella caps that were marinated in olive oil, sea salt, black pepper, garlic, and red wine vinegar for an hour before grilling.
The following Monday, grilled more ribeye, regular sweet potato and small crimini mushrooms on a skewer.
