Well... sure...
We do this as a side dish often since everyone likes it and it's quite easy.
! pound fresh spinach
1 large onion (yellow)
1/2 pound of sliced mushrooms (we like Portobellos)
2 or 3 thinly sliced cloves of garlic
1/4 cup extra-virgin olive oil
1/4 cup red wine or red wine vinegar
1 tablespoon lemon Zest
Juice from 1/2 lemon
1/2 cup grated Parmesan-Reggiano
1 teaspoon chilie pepper flakes (dried)
Salt and Pepper to taste
Slice onion (don't dice) and add to fairly hot olive oil along with the garlic. Cook until just translucent (about 3 to 5 minutes). Add mushrooms, don't overcook, just slightly wilted, maybe 5 minutes. Add red wine.
Add fresh spinach and lemon zest and cook just until the spinach wilts down. Don't overcook. Toss with grated cheese, lemon jusice and sprinkle pepper flakes to taste.
Some folks use kale instead of spinach, but spinach isn't as bitter as kale, in my opinion.
Serve as a side to any good meat dish (with the tomato-basil soup as a starter).
