Oh wow, these were sooo good! And they are filling enough to be the main course. Plus, it's really quick and easy. I served them with flavored rice. A side salad would be good, too. I got this recipe from a Slimming World magazine and the whole family, even my picky kids, loved it.
8 large, flat field mushrooms
Fry Light (or a spray like Pam or something)
4 garlic cloves
3 large tomatoes
6 oz/170 g mozzarella
11oz/312g fresh baby spinach
Gently clean the mushrooms and remove the stalks. Spray with Fry Light and put them on the grill rack, cap side up. Grill them on a moderate heat for 5 minutes. Turn them over and grill for another 5 minutes or until the shrooms start to weep. Mine "wept" well before 5 minutes was up. Meanwhile, peel and crush the garlic, cut the tomatoes into 8 slices and grate the mozzarella. Spray a skillet with Fry Light (or use some EVOO), let it get hot and then add the garlic and the spinach. Stir-fry for about 4 or 5 minutes, until the spinach iswilted but not a big soggy mess. Add the nutmeg and S&P to taste. Stir well.
Top the mushrooms with the spinach mixture. Put a tomatoe slice on top of each and sprinkle with the mozzarella. Place under a hot grill for 2 or 3 minute or until cheese is bubbly. Serve immediately as I can't see that they would be very nice reheated.
