Place rice and water in a medium-sized pot over medium-high heat, with no lid. Bring to a simmer - the edges should be bubbling, the middle should be rippling, and the surface will be foaming. Place a lid on, then turn the heat down to medium-low. Cook for 12 mins - do not lift the lid.
Cook veggies
Peel and mince the garlic. Deseed and finely dice the capsicum. Drain and rinse the black beans. Heat the oil in a large frypan on medium-high heat. Add the garlic and cook until fragrant, 1 min. Then add the capsicum, black beans, lentils, crushed tomatoes, tomato paste and Mexican seasoning and cook a further 5-8 mins, until slightly reduced.
Finish prep
Remove the veggie mixture from heat and add the red wine vinegar and honey. Stir to combine and season with salt and pepper. Peel and mash the avocado in a small bowl.
To serve
Divide the rice and Mexican lentils & black beans between bowls. Top with a dollop of the avocado.
