Caveat, my husband & I eat pasta for dinner a lot. (It is easy & available & there is nothing to thaw first.)
We occasionally saute squash & add it to the mix or even frozen sausage - the kind that you don't thaw first.
More often than not we add canned mushrooms.
The reason why this has come up is that Gypsy Quilter just shared a "free" sauce offer. For Bertoli (I think). Which made me say, that's nice but we only eat Paul Newman's sauce. Which made me think, "Anyone else out there use only one brand of sauce?"
(Our excuse - dietary restrictions mixed with taste - his tastes best to us out of the ones that we can eat.)
No "Pepsi Challenge" was used in this study of ours & we probably did not exhaust all of the options out there. It was more like - that tastes good, that will be the brand that we buy. (Oh by the way when it landed at "Big Lots" I bought A LOT! It was at most 1/2 the price as it is in the supermarket. We recently got some at a big box store that shall remain nameless also at just over 1/2 the supermarket price - so we stocked up again.)
Once or twice I have made the pasta sauce from scratch - not worth the time & effort - maybe that is a symptom of growing up on jarred sauce...
