batter:
1 egg (beaten)
1/3 cup milk
1 cup flour
salt, pepper, 
water if needed
5-6 zucchini- cut either steak fries style, or in 1/4 in. disks

stir batter ingredients until batter is smooth- if it's too thick add
water- otherwise add flour- i get it to where it kinda sticks to the
fork

dip zucchini in batter
deep-fry in preheated oil (i set the stove on medium high) until
batter is crispy
serve with that good tsatsiki that you've made already  :-)
