All a "good" sandwich needs is a little oven time to become a "GREAT" sandwich!
1 can (12 oz) white water-packed tuna, drained and flaked
1/2 cup frozen mixed vegetables, thawed and chopped
1/3 cup mayonnaise
2 tbsp finely chopped onion
1 tbsp ranch salad dressing mix
4 hamburger buns, split
In a large bowl, combine the first five ingredients. Spoon tuna mixture onto bun bottoms; replace tops.
Place each sandwich on a piece of heavy duty foil. Fold foil around each sandwich and seal tightly; place packets on a baking sheet.
Bake at 400 for 10-15 minutes or until heated through.
