Based on a Hungry Girl recipe.
Chop cucumber, cherry tomatoes, and (not too much) red onion into small cubes. Add one single-serve (or double-serve, if using as an entree) packet of flaked salmon or tuna (the dry kind works, but the ones packed with a bit of oil may make things a little tastier), and about one tablespoon each of dijon mustard and light mayonnaise. Mix well and serve.
Verdict: Refreshing and delicious, especially in small portions.
