Don’t just eat the tuna from the can, guys. Step it up by throwing it on top of an easy, nutrient-packed base made of fresh spinach, hard-boiled eggs, black olives, cherry tomatoes, ground pepper, and de-thawed frozen green beans. Use store-bought vinaigrette dressing, or whip up an easy homemade version by mixing the following ingredients: 2 tbsp. red wine vinegar; ¼ cup olive oil; a pinch of salt, black pepper, parsley and basil; ¼ tsp. dry mustard; and ½ clove of garlic, minced.
