Preheat the oven to 200 ºC.
Arrange the Sea Harvest Fish Fingers and McCain Smiles onto a baking tray and bake for 20 minutes until golden. Season with salt as soon as they come out of the oven.
To make a crunchy pink sauce, add the mayonnaise and tomato sauce to a small bowl then add half of the shredded lettuce and mix well to combine.
To assemble, add three fish fingers to the bottom half of a toasted slider roll, then top with slices of avocado. Top with crunchy pink sauce and a little more lettuce and then close up the slider. Thread a piece of cheese and tomato onto a toothpick and use it to secure the slider.
Serve with the sliders and Smiles and extra pink sauce for dipping.
