In a pan, add the extra virgin olive oil and heat it up.
Add the chicken breast strips and let them brown on each side.
Once the chicken is browned, add all the seasoning: brown sugar, paprika, garlic powder, onion powder, black pepper, oregano, salt and juice of half a lemon.
Toss around all the ingredients and let it cook on medium low until the chicken is ready.
In the meantime, prepare the tzatziki: chop the cucumber in small chunks and drain over some paper towels.
In a bowl, add the chopped cucumber, Greek yoghurt, crushed garlic cloves, chopped dill and combine.
Add the lemon juice, extra virgin olive oil and white vinegar, then season with salt and black pepper and set aside.
Prepare the trimmings for the chicken pitas: slice the red onion thinly, and do the same with the tomatoes and salad.
Once the chicken is ready, build your pita as you prefer: toast the pita bread slightly and fill it.
Serve immediately, piping hot, slathered in fresh tzatziki and packed with all the trimmings.
