Sooo....this does not help when you have a surfeit of tomatoes. But for when you don't have
enough. Or when the tomatoes aren't ripe yet (especially in colder climates with shorter growing seasons).
One of my other favorite salsa recipes is
rhubarb salsa. Rhubarb is a perfectly amazing substitute for tomatoes in salsa.
I know I've posted this elsewhere on permies, but couldn't easily find it.
The recipe I love is by the most amazing Erica Strauss, (author of
The Hands-On Home):

That was a sunlit picture of some rhubarb salsa I made on a camping trip in May earlier this year. The trickiest part (but still super easy) is cooking the rhubarb just enough to be soft, but not mushy.
For me, having savory rhubarb recipes is a huge win over all the sugary treats usually made with it.
