Shred your cucumber first, let it sit while you mix the rest of the ingredients. Before you add it into the bowl, pat it gently with some paper towel. You want to remove some liquids but not all.
In a medium bowl, combine the yogurt, dill, garlic, olive oil, salt, red wine vinegar and Sriracha, until smooth. Then toss in the cucumber shreds and mix. Taste and adjust if needed. Cover and refrigerate for at least 30 minutes.
Board:
Spread your spicy tzatziki on the board evenly. Top with your feta, olives, dill, paprika and a drizzle of olive oil.
Enjoy with baby bell peppers or oregano pita chips.
