The chayote is mostly used to cook. When cooked, chayote is usually handled like a summer squash; it is generally lightly cooked to retain the crispy consistency. Raw chayote may be added to salads or salsas, most often marinated with lemon or lime juice, but is often regarded as especially unpalatable and tough in texture. Whether raw or cooked, chayote is a good source of vitamin C. NUTRIENT CONTENT: Chayote squash is high in many nutrients — especially folate (vitamin B9) — while low in calories, carbs, and fat.
