Lightly brush 8 wells of a standard-size muffin pan with olive oil. Set aside.
Cut egg-roll wrappers into 4½-inch squares. Brush squares with olive oil. Press squares into prepared muffin pan, forming a basket shape.
Bake until wrappers are crispy and edges are golden brown, approximately 5 minutes. Remove from pan, and place on a wire rack to cool completely.
When ready to serve, divide lettuce, snow peas, cucumber, radish, bell pepper, and onion evenly among baskets. Drizzle with Hoisin Vinaigrette to taste.
