Preheat oven to 425°F. Line two baking sheets with parchment paper and set aside.
In a food processor, combine the tomato, garlic, green bell pepper, red bell pepper, and parsley. Pulse a few times so that the mixture is roughly chopped. Add the ground sirloin, tomato paste, red pepper paste (if using), aleppo pepper, salt, black pepper, paprika and cumin. Give it a few more pulses to evenly combine but don't over mix.
Working with one puff pastry square at a time, cut and shape into a classic "kite" danish shape. Prick with fork in the center and place on the prepared baking sheets.
Fill the center of each puff pastry square with 2 tablespoons or so of the meat mixture and spread out into an even layer in the center. Brush the edges with egg wash and bake until golden brown and puffed up, about 25 minutes. Remove from the oven and allow to cool slightly.
For the salad, in a large bowl, toss together tomato, red onion, parsley, lemon, olive oil, salt, sumac, aleppo and black pepper until well combined.
Serve the danish with a spoonful of salad on top and a wedge of lemon. Enjoy!
