Usually off, because I do prefer it that way, but it does depend on the dish. I use green chilis less than some of the others -- jalapenos, habaneros, cayenne, etc. The Weasel and I like it hot. (Still, I've never had the nerve to try datils. Even I have limits.)

I'd say ... try different things with yours. See what you think; see what you like. Some of the best fun with food is "winging it." (And Lord, I have made some wonderful meals doing that.)
