Jess, I believe GG is correct on the name of what you are searching for. Here is a recipe that sounds similar, perhaps you can use it to create what you are looking for. It came from Raúl Musibay's Cuban Food site. If you need a picadillo recipe, I think some have been posted, or post again, and I will post one.

Papas Rellenas

Fried Stuffed Potatoes


3 large potatoes, peeled and boiled
2 eggs beaten
dry bread crumbs
1 lb. Seasoned ground beef or picadillo
Flour (enough to roll the papas rellenas in)
cooking oil

Mash potatoes and let cool. Grab a handful of mashed potatoes, split the handful in half, making a little bowl out of each half. Stuff the indentation in each half with the ground beef or picadillo. Bring the two halves together and smooth to make a round ball, about the size of an overstuffed golf ball.

Dip the ball into the beaten egg, then roll in the flour until lightly covered. Dip the ball in the egg again and roll in the bread crumbs to coat thoroughly. Use a frying pan with enough oil to cover half the ball at a time. Heat oil to the frying stage and drop each papa rellena into the hot oil. Let it cook for about two minutes or until golden brown. Turn the balls and cook the other half in the same way. If you have a deep fat fryer, place a single layer of papas rellenas in the basket and cook for about 3 minutes, or until golden brown.
