Rinse the jasmine rice under cool water in a fine mesh strainer until the water runs clear.
In a medium saucepan, combine the rinsed rice and vegetable broth. Bring to a boil over medium-high heat.
Once boiling, reduce the heat to low, cover, and simmer for 15 minutes, or until the rice is tender and the liquid is absorbed. Remove from heat and let it sit for 5 minutes, covered.
Fluff the rice with a fork and mix in the lime juice, lime zest, garlic powder, cumin, salt, and pepper while the rice is still warm.
In a large mixing bowl, combine the fluffed rice with diced avocado, cilantro, cherry tomatoes, red onion, and jalapeño, if using. Gently fold all ingredients together to prevent mashing the avocado.
Adjust seasoning as needed, adding more lime juice, salt, or pepper to taste.
Notes
Serve in individual bowls, garnished with extra cilantro and lime wedges.
