Beef pita smash burger with quick tzatziki, cucumber-tomato-olive salad and feta

Cut English cucumber into thin strips and then small and rough; do not salt or squeeze it.

Mix the cucumber with non-fat Greek yogurt, a little garlic, salt, pepper, a little lemon and fresh dill; refrigerate.

For the salad, combine more cucumber cut the same way, Roma tomato, rough-chopped kalamata olives, a little garlic, salt, pepper, olive oil, dill and a big grip of parsley.

To a pound of ground beef add red onion, about a tablespoon of olive oil, kosher salt and pepper, Greek oregano, red pepper flakes, a little cumin and half a tablespoon of the paste; mix by hand - overworking does not matter since it is smashed.

Divide into three even-sized balls.

Heat oil on the griddle, set down a ball of beef, put a pita on top and press to smash.

Give it a little more time, avoiding too much grease - about one minute - then take it off.

Build mostly down the middle like a taco: tzatziki, salad, a few drops of fresh lemon, crumbled feta and more fresh dill; fold to eat.
