Put the rice in a pan with boiling water and simmer for 15 minutes until cooked.
Make the salsa by adding the chopped tomatoes, chopped jalapeno, chopped red onion, salt and pepper, lime juice and coriander to a bowl and mix well.
In a bowl, mix together the black beans, sweetcorn and all the spices. Heat a little oil in a pan and add the bean mixture. Gently cook for 3-4 minutes.
Make the guacamole by mashing the avocado in a bowl and then stirring in the coriander, salt, pepper and lime juice.
Drain the rice and then stir in the coriander and lime juice.
Build the burrito bowl up by dividing the shredded romaine lettuce between 2 bowls and then adding some rice, bean/sweetcorn mixture, salsa and guacamole. Finally, sprinkle over some chopped red pepper.
Instead of using romaine lettuce, why not try some other greens like spinach or kale for a nutritional boost?
If you don't want it to be vegan, some leftover chicken shredded on top is a good addition, or some chunks of your favourite cheese.
Don't have any black beans? You could use chickpeas, pinto beans or kidney beans instead.
Are you one of the few people out there that doesn't like guacamole? Fear not! You can still get all that delicious creamy flavour by using hummus instead. Even if you love avocado, make some avocado hummus to mix things up a bit.
Bored of regular salsa? Why not try using our Sweetcorn Salsa on this burrito bowl instead.
