Essentially a fancy name for “things on toast”, a tartine is a topless sandwich that can be piled high with delicious things with no threat of being squished together. I love the simplicity and elegance of this recipe: it is the perfect balance of sweet and sour, spicy and salty, and it feels special at the same time. Griddle and marinate the peaches ahead of time, if you like, and feel free to switch them for nectarines, apricots or whatever you have to hand that looks good for griddling.
