Wasabi mayonnaise: Mix wasabi and mayonnaise together in a bowl. Set aside.
Cut the avocado into slices and squeeze the other half of the lime over the avocado. Set aside.

Cut onions into rings. Mix flour and milk together in a bowl and dip onion in the mixture. Fry the dipped onion rings until golden brown in plenty of sunflower oil. Then place the rings on a sheet of kitchen paper to get rid of excess oil.
