Rinse the black beans under running water.
In a pan, heat the oil on medium heat and add the extra virgin olive oil. Add the corn kernels and cook for 5 minutes until toasted.
Slice the roasted red peppers and avocado.
Divide all the ingredients into the 4 meal prep containers: the cooked rice, black beans, chopped onions, corn kernels, and red peppers. Add the avocado just before serving, or if going to work, you can add it in the morning with a generous amount of lemon juice on top to avoid it going brown.
Sprinkle with freshly chopped cilantro.
Prepare the dressing: in a small bowl or a jar, mix the extra virgin olive oil, minced garlic, lime juice, water, maple syrup, salt, pepper, chopped cilantro leaves, and chili flakes to taste.
Keep the dressing in the fridge. Add it to the bowls just before serving (you can also add it a couple of hours in advance if needed).
