Oh wow, I will definitely be making this again. These open-faced sandwiches are good enough to serve to company. It took under half an hour and had a big flavor payoff. I think garlic mashed potatoes would be a nice accompaniment. Deborah recommends a pinot noir to go with this meal, but I think any red will do.
We had leftover hamburger buns that we needed to use up, so that's what we used for these sandwiches. The recipe calls for ciabbata or good crusty french bread, which would be fabulous.
Let's Get Started
Preheat the oven to 400º. You'll need one portobello mushroom per person. Using a damp paper towel, wipe off the cap of the mushroom. Remove the stem and the gills. The gills are those dark brown things inside the mushroom. A spoon works great to remove them. Drizzle the inside of the mushroom with olive oil and set on a baking dish. Chop 2 cloves of garlic together with a small handful of parsley leaves. Sprinkle the garlic-parsley mixture onto the inside of the mushroom (saving 1 t. of the mixture for later). Add salt and pepper and pop them in the oven for 8-10 minutes, until they are sizzling.
While they are cooking, wash and trim 1/3 pound greens. I used beet greens and curly kale. Any kind of braising greens will do. Heat 2 t. oil. Add the greens, the rest of the garlic-parsley mixture, a pinch of red pepper flakes and some salt. Saute the greens until they are tender. Taste for seasonings and doneness of the greens
Cut some fairly thick slices of fresh mozzarella. Put the mozzarella slices on top of the mushrooms, then layer the cooked greens on top of that. Bake for 5-7 minutes, until the cheese is melted. While that is baking, toast 1 thick slice of bread per person. Place the cooked mushrooms on top of the bread and serve.
Things I'd do differently next time
I just realized that the recipe called for 2 garlic cloves, a small handful of parsley, 1/3 pound of greens and 4 portobellos, but I only used 2 portobellos. If I were making this for 4 people, I think I'd increase the amount of garlic and parsley and greens, because those amounts worked perfectly for 2 portobellos.
I'd also try this with ciabatta or focaccia bread. It would also be wonderful with polenta or garlic mashed potatoes instead of the bread.
Cost to Prepare (for 2 people)
2 portobellos - $4.00
fresh mozzarella (4 slices) - $3.00
1/3 pound greens - $1.50 (organic)
2 slices bread - $.25
2 cloves garlic, red pepper flakes, salt, pepper, olive oil - negligible
TOTAL - $8.75 for 2
