In a mixing bowl, whisk together the Greek yogurt, grated garlic, lemon juice, and a pinch of salt until smooth and creamy. Set aside to allow flavors to meld.

Heat a large skillet over medium heat. Add the diced onion and sauté for 2-3 minutes until soft and translucent. Stir in the sweet paprika, garlic powder, and cumin, cooking for 2 additional minutes. Add ground beef and cook for about 10 minutes until browned. Season with salt, pepper, and tomato paste, simmering for another 2-3 minutes.

In a small saucepan, melt the butter over low heat. Mix in sweet paprika, stirring continuously for about 1 minute until it bubbles. Remove from heat.

In a serving bowl, combine cooked pasta with spiced beef mixture, tossing gently. Spoon creamy garlic yogurt over the top and drizzle with warm paprika butter. Garnish with cherry tomatoes, crumbled feta, and parsley.
