Preheat your oven to 400°F. In a small bowl, whisk together 2 large eggs, 1 tablespoon of half-and-half, and 1/8 teaspoon of ground pepper. Heat 1 1/2 teaspoons of olive oil in an 8-inch cast-iron skillet over medium-high heat. Add 1/4 cup of thinly sliced yellow onion and cook until softened. Add 1 small sliced zucchini, minced garlic, and crushed red pepper. Cook until the zucchini is tender-crisp and browned. Transfer the mixture to a plate. Wipe the pan clean and coat with the remaining olive oil. Place a 10-inch whole-wheat tortilla in the pan and top with the vegetable mixture and torn fresh basil.
