Preheat your oven to 200 degrees Celsius (or 180C fan/Gas 6). While the oven is heating, season 1-2 full chicken fillets with salt, pepper, and any other herbs to taste.
Place chicken in the oven and bake for 15-20 minutes or until it is cooked all the way through. Meanwhile, give 5-7 sweet potatoes a good wash and add them to the oven, baking them for 10-12 minutes.
Remove chicken from the oven and shred it with a fork. Add the shredded chicken to a large bowl with ½ cup of sweetcorn, 2-5 tbsp of mayonnaise, and salt and pepper to taste. Then, mash a whole avocado and mix it with a pinch of salt and pepper until you have a smooth guacamole.
Optional: Add a few handfuls of spinach for extra nutrition!
