Though summer doesn't arrive for another week, we've already begun to suffer the season's swelter. If you're looking for something to make for dinner that doesn't require turning your oven dials from the "off" position, try this tangy scallop ceviche from Ivy Stark of Dos Caminos. Like all ceviches, this one is "cooked" with lime juice instead of heat. (Technically, the acid denatures the proteins, resulting in seafood that's firm and opaque.)
