Made this for a Mexican-themed party and they were gone in instants. Used real tostadas and just broke them in 4 pieces and put one shrimp on each piece to make a bite-size passable appetizer. Also used Mexican cheese instead of cheddar/jack, though it looked nicer, I think I'd go back to a more meltable cheese next time.
I used regular tostadas and mexican cheese also for this dish. It was quite delicious! Thank you.
