For toasted buns, heat a grill pan or skillet over medium heat. Brush the outside of the rolls with olive oil. Toast the buns until slightly golden, about 1 minute per side. Brush vegan butter on the inside of each bun.
If you have leftover vegan lobster salad mixture, you could add it as a side to another meal, or even better, roll it into a vegan sushi roll or even fry up to make crab cake mix!
