When travelling my grandmother and I came across the equation for the perfect salad-as-meal: leafy vegetable + other vegetable + fruit + nut + cheese + dressing (+ carb). This salad is one example out of many variants of that theme.
Leafy vegetable - mixed lettuce; Other vegetable - sweet potato; fruit - sliced pear, apple, grapes... you get the idea. The possibilities are endless.
The antipasto mix can either be bought, or you can use a combination of olives, sundried tomatoes, fetta cheese, marinated mushrooms... or if nothing of that kind is handy, just dress with olive oil, toss and serve.
