It’s hard to go wrong when the ingredients include cilantro, avocado, jalapeños, lime, garlic, and sushi-grade tuna. The recipe calls for lightly searing raw tuna on each side and then serving. I love tuna done this way, but the tuna has to be very high quality. My parents, on the other hand, have no intention of ever eating raw fish, sushi-grade or not. They cook their fish all the way through, so it is a little translucent in the middle, but definitely cooked. They loved it.
