Canned crescent rolls
Hot dogs (I like turkey sausage)
Sliced American cheese
Tear cheese into small strips.
Slice an opening in the middle of each hot dog, trying not to cut all the way through, leaving about a half inch uncut on each end (prevents cheese from leaking out).
Stuff a cheese strip or two inside each hotdog.
Separate the crescent rolls. These were generic and didn't pull apart as well as what I'm used to. I had to do some patching like Ruthy has talked about with pie crusts! :)
Lay stuffed hotdog at wide end and roll toward the point of the crescent roll.
Spray baking sheet with cooking spray. Put the wrapped hotdogs on the sheet cheese-side-up. Bake according to package directions. Although they'll probably need to bake a bit longer. I don't remember how long, since my book club ladies had arrived by that time. We were chatting so I didn't pay attention. :) I think it was about 10 extra minutes, long enough to make sure they weren't doughy.
I only snapped a shot in the oven. No finished photo since I was occupied. I sliced them in quarters for the appetizer size (and then, since I hadn't had dinner either, proceeded to eat four! LOL). Kids just grabbed two or three whole hotdogs each. Yep, hungry from tennis. :)
