Start by preparing your veggies: Slice your red onion and bell pepper (being sure to remove the seeds) and add them to a large bowl.
Next, pour the olive oil over the veggies and add in all of your spices, tossing until the veggies are fully coated in the spices.
Next, heat a tablespoon of olive oil, in a pan, on the stove. Once the pan is hot, toss in your onion and bell pepper mixture and cook until the veggies have softened – this should take about 7 minutes.
While the veggies are cooking, prepare your rice. Rinse it thoroughly, then add it to a pot on the stove, along with water or broth.
Bring the rice to a gentle boil, then reduce the heat to low, cover the pot, and let the rice cook for 20 minutes, until fluffy and tender.
Once your veggies have cooked through, transfer them to a plate or bowl and then place your pan back on the stove. Add in another tablespoon of olive oil, and once the pan is hot again, add in your peeled and deveined shrimp.
Cook the shrimp until they're no longer translucent – this should take about 4 minutes.
Once the shrimp are done, remove them from the heat and assemble your fajita bowls: fluff your rice and add it to a bowl, then add in your onions, bell peppers, and shrimp.
Mix them together, then serve and enjoy!
