So, before I forget about the fabulous meal that we had tonight, let me jot it down. Because it's not written anywhere else!
Pre-heat oven to 350
De-stem three portabello mushrooms and place upside down in baking dish to fit
Some olive oil, in a skillet
1 small onion, chopped as you like it and set to saute
2 cloves of garlic (or whatever you've got), prepared as you do and set with onion
1 lb of turkey burger (only about 1/3 to be used for this recipe -- freeze rest for chili), browned with onion and garlic
1 leftover baguette chunk from pan-sandwich shop, pulverized in processor
3 slices of provolone cheese, pulverized in processor (apart from bread)
Mix together in bowl
Drain turkey-onion-garlic mixture, and measure out 1/2 cup (or so)
Mix together with bread crumb-cheese mixture
Add some worcestire and soy to the top of the mushrooms; scoop mixture into mushrooms, packing lightly. Top with a splash of the w-sauce, if desired.
Bake for 15-20 minutes. Serve.
