Add 1 cup breadcrumbs into a separate bowl, season with a ¼ tsp (1.5 grams) sea salt and mix together
Heat a large fry pan with with medium heat and add in ½ cup sunflower oil
While the oil is heating, coat the slices of zucchini, first into the batter and then into the breadcrumbs, making sure they are evenly coated
After heating the oil for about 5 minutes, start adding the coated slices of zucchini into the pan, make sure they´re all in a single layer, cook in batches, after 75 to 90 seconds flip to cook the other side, after another 75 to 90 seconds remove them from the pan and transfer to a dish with paper towels
While the zucchini bites are still hot, finely shred in some Manchego cheese over them
Continue to cook your zucchini in the same method until done
