A suitable choice for lunch is a mixed salad, and an appropriate quantity might be 12 oz. Weigh foods until you are used to estimating the quantities by eye— it's larger than you are used to. Get in the habit of thinking that a salad is often in two parts: The salad vegetables, comprised uniquely of foods from Food Group 3 (Non-starchy Vegetables), and some additions of protein-rich foods from Food Group 6 (Meat, Poultry, Eggs, and Fish). You can add tuna or chicken breast, for example, to the salad or eat as a side dish. Use a simple homemade vinaigrette of mustard, olive oil, lemon juice, and vinegar.
