Preheat oven to 400. Place won ton wrappers in miniature muffin cups and press the pastry to fit the shape of the cup. Place them in the oven and bake 6 minutes, or until golden brown and crisp. Meanwhile, pour chili into microwave safe bowl. Cover and cook on high for 3 minutes, stirring once. While the chili is heating, rinse the radishes and thinly slice. When pastry cups are done, remove from the oven and stir in the chili. Garnish each with about 1 tbsp shredded lettuce and a tiny dollop of sour cream. Top with a few radish slices. Serve immediately.
