Stir together rice, water, and broth mix in Multipurpose Steamer. Top with tray; microwave uncovered, on high, 16–18 min.
Meanwhile, drain and rinse chickpeas. Place in bowl with edamame, lime juice, and seasoning. Toss to combine.
Cut cucumber into rounds. Slice avocado.
Once cooked, divide half of rice between four bowls; reserve remaining rice for use at a later date. Arrange chickpea mixture, cucumbers, avocado, snow peas, and lettuce in bowls. Drizzle dressing on top; add additional toppings, if desired.
Tip: Use remaining rice to make burritos the next day.
