Cook rice as per packet instruction, drain and put aside.
Meanwhile, thinly slice the onion and pepper. Add oil to a large frying pan and on a medium heat, gently fry the onion and pepper until softened. Add in chipotle paste and spices and stir until vegetables are coated.
Add in the chopped tomatoes, kidney beans and black beans. Use hot water to rinse out the kidney bean can and add to the pan.
Add salt and pepper to taste.
If serving straight away; warm tortilla wraps, add a layer of rice and a layer of bean mixture. Add cheese and any other toppings you fancy and roll up into a burrito.
I like to batch cook these and freeze them for lunches. To do this you need to cool down the rice. I do this by spreading out the rice in a thin layer on a baking sheet and putting it in the freezer for 10-20 minutes. I also cool down the burrito filling by putting it in the fridge.
Once both fillings are cooled, build the burritos in the same way as above, roll them and wrap in grease proof paper. Put each burrito either in a Tupperware box or food bag and place in the freezer.
Defrost the burritos the night before and then at lunch time, microwave for 2-3 minutes and enjoy!
