Step 1

Preheat the broiler to High. Broil the pita until crisp, 1 to 2 minutes on each side.

Step 2

Meanwhile, coat a small nonstick skillet with cooking spray. Heat the pan over medium heat. Crack the egg into the pan; sprinkle with a pinch each of salt and pepper. Cook until desired degree of doneness, 3 to 4 minutes.

Step 3

While the egg cooks, coat a medium nonstick skillet with cooking spray. Heat the pan over medium-high heat. Add the spinach, zucchini, tomatoes, and remaining pinch each of salt and pepper; cook, tossing frequently with tongs, until just wilted, 1 to 2 minutes. Arrange the spinach mixture on the pita; sprinkle with feta and top with the egg.
