I cannot often enough extol the virtues of JustMayo. Although the original plain flavor tastes great, and is very versatile, garlic mayo is my current favorite.
Mix mayo with chickpeas, stir in peas being careful not to crush them. Season to taste with salt and pepper. Gently fold in chive blossoms. You can eat the salad as-is, or make a sandwich with lightly toasted bread and baby romaine, or your favorite sandwich greens.
