Bring some oil to a simmer in a pot. While it's heating up, crush the corn chips into crumbs with a food processor or a mortar and pestle. Transfer the crumbs to a shallow dish, add about 1/3 cup water and stir to make a batter.
Use a fork to pick out the raviolis from the tomato sauce they're smothered in. Coat them in the batter and fry them in the oil until they have a golden crust, 3 to 5 minutes. Remove the ravioli from the oil, pat off the excess oil with a paper towel and serve with some of the tomato sauce from the can.
