Celery Free Pesto-Walnut Artichoke Olive Crostini

These crostini are the kind of appetizer that disappears from the platter before you've even finished arranging them. Toasted whole-grain rounds get loaded with a bright, herby walnut pesto — made entirely from scratch in a food processor with fresh basil, raw walnuts, garlic, and lemon juice — then topped with a tangy mix of chopped artichoke hearts and buttery Castelvetrano olives. Every component is naturally free from celery and celery-derived ingredients, so there's no need to scrutinize labels or swap anything out. The walnut pesto brings a rich, nutty depth that plays beautifully against the briny olives and the mild, slightly sweet artichoke. A hit of red pepper flakes and a final scatter of fresh basil take the whole thing over the top. This is the kind of crowd-pleasing starter that looks impressive but comes together with minimal effort and zero stress.
