If you don’t like scallops, jumbo shrimp would also be great. Chicken works too, or have you seen the vegan “scallops” with hearts of palm? You basically cut them into thick rounds, season and sear them on both sides. If you can find larger scallops, I find they make a nicer presentation, but any size will do.

Spaghetti, angel hair, bucatini, whatever long pasta you like works here.
