What to do with hamburgers when you're out of ketchup

... they're crispy. • Slice some tomatoes • Salt and vinegar the tomatoes • Put your hamburger together (fold the squash greens to fit; expect them to crumble partially as you do), and eat. The squash greens were pretty good on this, actually. FYI, I like ketchup, pickles, onions, and mayonnaise on hambugers. recipe_ hamburger_ ketchup_ chilacayote_ tomato_ cheese_ salt_ vinegar_ greens_
