First, prepare the jackfruit carnitas. Drain the brine and rinse well.
In a medium nonstick pot, heat up the olive oil and chopped onion over medium-high heat. Add in the rinsed jackfruit and saute, stirring often, for 5-7 minutes, until onions are softened and translucent.
Add in the can of enchilada sauce, turn heat down to low, and cover the pot. Let jackfruit mixture simmer for 20-30 minutes, until sauce is thickened and jackfruit pieces are falling apart.
To make the beans, pour 1 can of black beans (including the liquid) into a small nonstick pot. Add in all the spices, and turn heat to medium. Allow to simmer for 15-20 min, stirring occasionally, until beans become creamy and liquid has mostly evaporated.
While the jackfruit and beans cook, prepare quinoa according to package directions.
To make the fajita vegetables, heat a saute pan over medium-high with the olive oil. Add in the sliced onion and peppers, and season with some salt. Cook, stirring often, until vegetables are soft and golden brown.
To serve, divide the quinoa among 4 bowls. Top with some beans, jackfruit carnitas, fajita vegetables, avocado, fresh cilantro, and a squeeze of lime. Enjoy immediately!
