1/4 c. cream cheese
1/4 c. salad dressing
1 egg
2 tbsp. finely chopped onion
1 tbsp. butter
1/3 c. grated cheese

Take hamburger buns apart to make 4 halves. Brown tops of buns under broiler and set aside.

In medium saucepan cook onions in 1 tablespoon butter. Add egg and scramble it up. Remove pan from heat and add tuna, cream cheese and salad dressing, salt, pepper and grated cheese. Mix until well blended.

Top each bun with a scoop of tuna mixture, a slice of tomato and a generous sprinkling of grated cheese. Place in 400 degree oven until hot and bubbly.
