I repete, it is not my recipe but since I had never heard of one like this, thought maybe you had not either.
My Daughter lives in Texas and I think I'll ask her if she's ever heard of it...or maybe her MIL (since she was born in TX).
P.S. Have a variation or add on to this recipe posted below by a JAP member...Vicky Searcy.
I will add it to a NOTE at the end of the recipe.
THANKS VICKY FOR YOUR FEEDBACK ON THE RECIPE.

Add grated cheeses.
Next day, take out of refrig and bring to room temperature before serving.
I will have to work up enough nerve to give this one a try...=;D
