Here’s a creative way to use leftover cooked spaghetti: try mixing it with eggs for a filling Italian omelet. If you don’t want to buy separate bunches of fresh herbs, look for an Italian blend package that may contain some of each or use one-third the amount of dried.

Ingredients

Ingredient Checklist

• 8 ounces uncooked whole-wheat spaghetti or 4 cups cooked
• 4 teaspoons extra-virgin olive oil
• 3 medium onions, chopped
• 4 large eggs
• ½ cup nonfat milk
• ⅓ cup freshly grated Parmesan cheese
• 2 tablespoons chopped fresh parsley
• 2 tablespoons chopped fresh basil
• 1 teaspoon salt
• ½ teaspoon freshly ground pepper
• 1 tomato, diced (optional)

• Step 1Cook spaghetti in a large pot of boiling water until just tender, 8 to 10 minutes or according to package directions. Drain and refresh with cold water. (Skip this step if using leftover spaghetti.)Step 2Meanwhile, heat oil in a large ovenproof nonstick skillet over medium heat. Add onions and cook, stirring occasionally, until golden, 10 to 12 minutes. Transfer to a bowl and let cool slightly. Wipe out the pan.Step 3Whisk eggs and milk in a large bowl. Stir in the onions, Parmesan, parsley, basil, salt and pepper. Add the spaghetti.Step 4Coat the pan well with cooking spray and place over medium heat. Pour in the egg mixture and distribute evenly in the pan. Cook until the underside is golden, turning the pan around on the burner occasionally to ensure even cooking, 3 to 5 minutes.Step 5Invert a large platter over the pan, grasp the platter and pan with oven mitts and carefully turn over. Lift off the pan and spray it again with cooking spray. Slide the frittata back into the pan and cook until the bottom is golden. Slide the frittata onto the platter. Garnish with tomato, if using.
