Spread vegan mayonnaise lightly on both sides of toasted bread.
Spread pesto over the mayonnaise.
On bottom slice of bread, arrange deli slices first, then top with greens and avocado slices. Add sprouts and sprinkle with your choice of vegan or dairy cheese.
Put sandwich sides together. Smash down, if necessary, to keep all the ingredients together.
Slice in half if desired. Enjoy!
