To keep this antipasto salad at its best for meal prep, store the meats, cheeses, artichokes, peppers, olives, and dressing together in an airtight container and refrigerate for up to 3 days, then toss with fresh arugula and basil right before serving. Choose low-carb or zero-sugar cured meats and check labels on marinated artichokes and roasted peppers to avoid added sugars. For a larger crowd, the recipe doubles easily and can be served on a big platter with the arugula and basil layered underneath or around the edges. If you prefer a milder flavor, reduce the red pepper flakes and Italian seasoning slightly and add more olive oil for a richer, smoother dressing.
