This was very good and I think would have been even better if I'd had chili tuna available. I improvised by using a little sesame-chili oil when I sauteed the veg. but could have used more (I was afraid to use too much!) I had enough veg. & tuna left over to make a third pizza (and I didn't even use the full amounts of veg. called for). I love to use naan bread for pizza crust so did that here instead of the pita and used monterey jack cheese. Thanks for the nice, healthy dinner!
