Last night I processed my vegetable mixture for 90 minutes. This is a long time. This morning I did a bit more research and found:
"All tomato-vegetable mixtures must be processed in a pressure canner, according to the directions for the vegetable in the mixture that has the longest processing time."

Onions require 40 minutes. I think that was my longest vegetable. Zucchini is no longer listed alone but tomatoes with zucchini are 35 minutes. So I think I could have processed for 40 minutes. So this gal is still learning. My mixture turned out great and even though it was really cooked I know it will be wonderful this winter.
