I make sauce and salsa every year from my garden. I toss in most of whatever I am growing. There's always a few hearts (Kosovo is a staple for me) and beefsteaks. One year I grew lots of yellow, orange tomatoes and had a funky looking, very tasty sauce!
I would recommend Cuore Antico di Acqui Termi. It is an amazing tomato - as a paste, yes, but edible on it's own as well. I grew it last year for the first time. Here it is next to Howard German. I do not have seed this year, but if you check back with me in the fall, I hope to have more.
