Squeeze the excess water out of the zucchini and pat dry with a paper towel.
Roughly chop the basil and mix with the zucchini, feta, lemon zest, salt, pepper, and cumin.
In a separate bowl, whisk together the egg and slowly add the flour.
Pour over the zucchini mix and combine.
Heat up so olive oil in a pan, and scoop the mixture onto the pan. Cook for a couple of minutes each side, until browned.
