There is something so fun about these sandwiches! It's the ranch dressing mix that provides the WOW factor.
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 bottom buns; replace tops.
Place each sandwich on a piece of heavy-duty foil. Fold foil around each sammie and seal tightly; place packets on a baking sheet.
Bake at 400 for 10-15 mintues or until heated through.
