Here is a simple snack or meal add on. I heat up my George Forman grill and put portabello or other med to large size mushroom pieces on it to cook about 5-10 min (check them), I don't use oil but you could. When they are cooked thru put them on a plate, close together, lay 1 roasted red pepper (from a jar or you cook your own) on top and break feta cheese all over it. I heat it in the microwave on high for 30 seconds and voilą!! It is super colorful and meaty and satisfying to nosh on.
I buy a bottle of pickled roasted red peppers in the pickle aisle for about 6.00 Canadian and a container of goat feta cheese for the same, 6.00. I use whatever mushrooms look best, sometimes portabello sometimes white 'button' . If you are new to feta cheese be sure to dump the water it comes in and refresh the tub every second day or so to keep it fresh.
