Marinate the steak for as long as possible, overnight works perfectly for added flavour.
When cooking the steak, make sure the heat is not too high, you don’t want the spices to burn. Depending on the thickness of the steak, cook 4 mins each side then repeat 2 mins each side.
For easy reheating, store the lettuce, salsa, sweetcorn, beans and avocado sauce separately then add to the bowl when ready to eat.
You can make the salsa and avocado sauce in advance and store in the fridge for a few days for future use.
