Make the meat filling: combine the feta, ground chicken, grated onion, grated garlic, salt, pepper, fresh mint, fresh basil and minced jalapeno in a bowl and mix well with your hands or a spatula to combine.
Divide the meat filling into 6 portions. Shape each portion into a semi-circle that's just a bit smaller than half of a pita.
Carefully open each pita half and put a flattened portion of meat into each.
Close the pita and gently press to make the pita flat.
Fry or grill until crispy and golden brown.
Serve with Greek tzatziki sauce.
