The key to making a satisfying salad without a lot of calories is to start with about two cups of greens (maybe baby spinach), then add lots of colorful vegetables, such as diced cucumbers, bell peppers and artichoke hearts. Next, add a source of lean protein (which will help keep you full), like beans, grilled chicken or tuna (hold the mayo). Include a small serving of healthy whole-grain carbs, such as quinoa or a whole-wheat pita on the side—the fiber will also help you feel fuller longer. Finally, add a little bit of dressing for flavor—no more than two tablespoons.
