Roast the garlic. This is very easy to do: simply trim the tops of whole garlic bulbs to expose the cloves, set on a piece of foil, and drizzle with olive oil (about 1 tsp).
Stir in spinach, and sauté 2 minutes, or until wilted. Season with salt and pepper/crushed red pepper. Add 1 Tbs. Parmesan cheese to pan, and remove from heat.
