In the same skillet sauté the broccolini, shiitake mushrooms, yellow bell peppers, snap peas, edamame and green onion in 1/4 cup olive oil until tender/crisp.
In a large bowl combine the sauce ingredients.
Cook the pasta according to package directions. Drain.
Toss the cooked pasta with the sauce, vegetables and toasted sesame seeds. Add salt and pepper to taste. Serve hot or at room temperature.
