Start the beans first. If cooking from scratch in an Instant Pot, get them going first they take about 60 minutes total. If you're using canned beans, simply drain and rinse them. Done. No further action required.
Cook the rice. Cilantro lime rice takes 25–30 minutes from start to finish, so start it after the beans are sorted. If you're using canned beans, you can start the rice straight away since you're not waiting on anything.
Sauté the fajita vegetables. While the rice cooks, heat olive oil or water in a large skillet over medium heat. Add the sliced onions, bell peppers, oregano, and a pinch of salt. Sauté for about 10 minutes, stirring occasionally, until everything is soft, tender, and slightly caramelized. Remove from heat.
Assemble the bowls. In each bowl, add approximately ¾ cup of rice, ¾ cup of black beans, ¼ to ⅓ cup of corn salsa or pico de gallo, and one quarter of the fajita mixture. Add a handful of shredded romaine and a quarter of an avocado, mashed or sliced.
Finish and serve. Squeeze fresh lime juice over each bowl, add a pinch of salt and a dash of red pepper flakes. Add any additional toppings and serve immediately.
