Cook the pasta by bringing a pot of salted water to a boil, then follow the cooking instructions on the package. Drain the pasta and rinse it with cold water to cool it off and halt the cooking process.
Steam or boil the edamame for 3-5 minutes, then rinse with cold water to keep them fresh and bright green.
Slice cherry tomatoes, dice the red onion, chop the bell peppers and cucumber, and roughly chop the spinach.
In a small bowl, whisk together olive oil, lemon juice, tamari (or soy sauce), sesame seeds, garlic powder, salt, and black pepper.
In a large mixing bowl, combine the pasta, edamame, fresh veggies, and greens. Pour the dressing over the salad and toss it until everything is well coated.
Let the salad sit for 5-10 minutes to absorb flavors, then serve immediately or refrigerate for later.
