Fill a medium saucepan with 2 inches of water, and place a steamer insert inside. Bring to a boil, and add beans. Steam, covered, for 3 minutes, then add corn and peas, and steam 2 minutes more, or until beans are tender-crisp. Let cool. Combine in a large bowl with tomatoes, radishes, shallots, almonds and feta. Dress with prepared vinaigrette and serve on salad greens.
Preheat oven to 350°F. Heat 1 tablespoon unsalted butter in a small skillet. As butter melts, stir in 1/8 teaspoon chili powder and 1/8 teaspoon salt. Stir in 1/4 cup roughly chopped almonds. Spread almonds on a baking sheet lined with foil, and bake 10 to 15 minutes, until fragrant. Let cool before placing on salad.
