These delicious hors d'oeuvres can be served anytime. You may prepare the patties in advance and refrigerate without cooking. Fry them when ready to eat. They can be reheated in the microwave oven (1 to 2 minutes) or in the conventional oven (10 minutes at 400 degrees F) or in a skillet. You can modify the vegetables and spices as desired.

I prefer a good portabella mushroom sandwich to a typical veggie burger anyday, and this one is excellent. It's juicy, garlicky and cheesy, and really quick. Try it on the grill in the summer, on grilled French bread with garden-fresh tomato ... mmmmmmm! Prep time includes marinating mushrooms.
