Zucchini-Onion Frittata

I found this one on Cooking Light's website. I'm a Cooking Light whore and am proud of it! Frittatas are so very easy and naturally lend themselves to the whims of the cook's palate because so many ingredients can be substituted depending on what's in the fridge, the garden, the season, in general. Enjoy!

I'd suggest using a spring mix with a simple vinaigrette of olive oil, lemon juice, sea salt, and pepper to round out a meal.

Ingredients
3 tablespoons butter

2 tablespoons vegetable oil

2 medium zucchini, thinly sliced

1 medium onion, cut in half and sliced

1/2 cup grated Parmesan cheese, divided

8 large eggs

1/4 cup milk

1 teaspoon salt

1/2 teaspoon pepper

1/4 cup chopped fresh basil

Garnish: chopped seeded plum tomatoes

Preparation

Melt butter with oil in a 12-inch ovenproof skillet over medium-high heat; add zucchini and onion, and sauté 12 to 14 minutes or until onion is tender. Remove from heat, and stir in 1/4 cup grated Parmesan cheese.

Whisk together eggs and next 3 ingredients at least 1 minute or until well blended. Pour over vegetable mixture.
Bake at 350° for 13 to 15 minutes or until set; increase oven temperature to broil, and broil 5 1/2 inches from heat 1 to 2 minutes or until edges are lightly browned. Sprinkle evenly with remaining 1/4 cup grated Parmesan cheese and basil. Garnish, if desired.

Lightened Zucchini-Onion Frittata:

Reduce butter to 1 tablespoon, and omit oil.

Sauté zucchini and onion as directed; remove from heat. Reduce grated Parmesan cheese to 1/4 cup, stirring 2 tablespoons into vegetable mixture.

Substitute 1 (15-ounce) carton garden vegetable egg substitute for 8 eggs and 1/4 cup low-fat milk for 1/4 cup milk, and whisk together with salt and pepper. Pour over vegetable mixture.

Bake as directed; do not broil. Sprinkle evenly with remaining 2 tablespoons grated Parmesan cheese and basil. Garnish, if desired.
