Classic basil pesto never goes out of style, but tonight’s scallion pesto is just the fun, dynamic condiment we’ve been craving. The scallions are finely chopped, then mixed with sesame oil and seeds, ginger, sugar, lime juice, and sriracha. The result? A tangy, sweet, savory, and spicy flavor explosion that provides just the right contrast to mild tilapia fillets, fluffy ginger rice, and snappy green beans.
