Ok.. Here in Albuquerque, they aren't hard to find, but back in my college days on the east side of the side (might as well be Texas), there were none.
So I took a piece of cardboard box, bent it in half and covered it with tin foil. Just remember to pat them with a paper towel for the excess oil.
Worked like a charm every time!
theres a grocery store here not far south of albuquerque with a whole bin full of the things, i coulda gotten you one for $5
