To make Polenta Crepes, place all ingredients into the Thermomix bowl and mix 20 sec/speed 6. Scrape and repeat if needed.
Allow mixture to rest for 20 minutes.
Heat shallow crepe pan, butter the pan with a very small amount of butter and pour batter into hot pan. Never pour batter into unheated pan as it will stick.
Turn over crepe once edges start to lift.
Preheat oven to 180°C and line an oven proof dish with baking paper.
To assemble crepes, spread some of the salsa and sour cream onto crepes and top with chicken, beans and half of the cheese.
Fold up crepes into a parcel and place in baking dish.
Top with remaining salsa and cheese. Bake for 15-20 minutes.
Garnish with coriander, chilli, spring onion, smashed avocado and lime cheeks.
