Slow-roasted tomatoes are a staple in my kitchen. Once tomatoes sit in the heat and concentrate their natural sugars, they become these squishy, sweet little treats that improve just about anything they touch. Tossing in pasta or placing on a sandwich, sure, but also blended up in soups and sauces – or, at least once each summer, just enjoyed with some bread and hummus for a lazy snack-dinner on the back patio.

If you’re the sort of person who is willing to suspend gratification, you can keep the slow-roasted tomatoes jarred or frozen and break them out when winter rolls around and you’re craving a hit of summer juiciness. I wouldn’t personally know about that, of course; they’ve never lasted that long around me.
