In
a skillet over a medium heat warm the rice. Once warmed transfer to a bowl and place in the oven to keep warm.
Turn the heat up to high and add a splash of olive oil to your pan.
Season the beef with salt and pepper and cook on high heat for about 3 minutes per side until the outside is charred.
Set aside to rest the beef before you slice it.
Shred the lettuce and warm the corn and beans in the skillet which will still be hot from the beef.
Wipe the skillet out with a paper towel first if you need to.
Assemble the bowls starting with the rice, lettuce, beef and beans, corn, tomatoes, avocado and some cheese. Serve with some tortilla chips if you like.
