Preheat the oven to 250 degrees F. Place the pita on a baking sheet and transfer to the oven to warm the pita.
To a small bowl, combined the diced cucumber, cherry tomatoes, lemon juice, a few pinches of salt, crushed red pepper, Italian parsley and mint.
Using a grill or grill pan, bring the heat to medium-high. Brush the squash with a bit of olive oil. Cook on each side for about 2 to 3 minutes, until the squash has softened slightly and you begin to see grill marks. Transfer to a plate and sprinkle with a few pinches of salt.
To assemble the gyros, grab the tzatziki from the fridge. Add a dollop to the center of the pita and spread it around into an even layer. Add a few slices of squash, top with a few spoonfuls of tomato and cucumber salad and a handful of microgreens. If you want to make it extra cute, wrap it in sandwich paper and tie it with a piece of twine.
