Joe's Special (Skillet Frittata) (4 servings) 6 large eggs 1/2 teaspoon dried basil 1/2 teaspoon dried oregano 1/2 teaspoon fresh ground black pepper 1/2 teaspoon salt 1/8 teaspoon FRESHLY grated nutmeg 1 Tablespoon olive oil 1 Tablespoon unsalted butter 1 medium yellow onion - diced 6 button mushrooms - sliced 3/4 pound lean ground beef (preferably chili grind) 3/4 to 1 pound fresh spinach - trimmed of stems and chopped (or one 10-ounce package frozen chopped spinach that's been thawed and drained WELL) 3/4 cup grated FRESH Parmesan cheese Break open the eggs into a small bowl; add in the basil, oregano, Nutmeg, salt and pepper; whisk to combine (you should still see large bubbles); set aside. Heat the oil and butter in a large skillet over medium heat until the butter melts. Add in the onion and mushrooms; stir/saute for 4 minutes or until soft but not beginning to brown. Add in the ground beef; continue cooking until meat is browned, breaking meat into small pieces as it cooks. Cover with the spinach, place the lid over the mixture, and cook for about 3 minutes, just until the spinach wilts (if using thawed frozen spinach, cook, covered, for 1 minute). Stir the spinach into the meat, cooking briefly to eliminate excess liquid if the mixture seems watery. Pour the egg mixture over all; stirring with a spatula from the bottom until the eggs begin to set. Remove from heat and stir a few more times; Sprinkle in the grated Parmesan.
