Creamed Tuna on Toast (now known as Toasty Bake) Name change courtesy of Payson :)

4 T. butter/margarine
4 T. flour
1/2 t. salt
2 c. milk
1 can tuna fish (drained)

Melt the butter in a sauce pan.  Add flour and salt and stir until flour is cooked in the butter.  Remove from the heat and add 1/4 c. milk.  Stir until smooth.  Add the rest of the milk slowly, whisking together until smooth.  Return to heat and cook slowly until it reaches the boiling point.  Add tuna.

Serves 3, and covers 6 slices of toast.

This is a family favorite.  I usually double it.
