Love making spicy giardiniera, been making enough for my to put some in my lunch every day. Recent batch I added fennel bulb, which based on it by itself I was really worried it would be too licoricy, but it's actually really subtle. Overall, I like mixing up what veg a throw in each batch. Got cheap bulk seeds for it at my local Asian market btw, waaaay cheaper than any other store near me.

Other than that, I've been wanting to try something fermented, like kimchi, but haven't gotten around to it yet.
