Similar to canned tuna, sardines from a tin are an incredibly versatile convenience item to keep in your cupboard, delivering ample protein and heart-healthy fats as well as singular flavor. In this simple salad, the sardines are broken into pieces and folded into a mixture of chopped tomatoes, onions, roasted peppers, and fresh chives. A drizzle of olive oil and splash or two of vinegar (your choice) is all that's needed for a "dressing."
