Step 1Heat the oven to 350 degrees. Grease a shallow 6-cup oven-proof dish.
Step 2Place the spinach in a microwave-safe bowl with a little water, cover and microwave until wilted, 2 to 3 minutes. Drain and chop.
Step 3Toss the spinach with the zucchini, carrot, green onions, eggs, oil, matzo meal, chicken bouillon, basil, oregano, parsley and garlic. Pack into the dish.
Step 4Bake until slightly puffy and lightly browned, 25 to 35 minutes. Serve hot or warm.
