I forget how long I do onion rings, didn't make myself a chart like i should have. I just check them after a couple minutes and flip them. I tried doing a french bread pizza tonight. Ran it at 380 and after 3 minutes i gave it a check. Pepperonis had blown off, haha. Replaced them and ran it for another minute, cheese was melted and it was crisp so started eating, very center of the pizza wasn't done so ate half and threw it back in for 2 minutes and finished eating.
Not sure I could get the center done without burning the the edges and top. Need to experiment more. The jalapeno poppers turned out good though.
