Step 1

Prepare: Thoroughly pat shrimp dry using paper towels. Stir shrimp, melted butter, salt, and pepper in bowl until shrimp are well-coated with butter; set aside. Verify all other ingredients are measured, prepared, and ready to go.

Step 2

Sear Shrimp: Heat skillet over medium-high heat for a few minutes until hot. Use tongs to add shrimp to hot skillet in single layer, working in batches if skillet cannot fit all at once. Cook shrimp for a minute or until they start to become pink around edges, then flip and cook until opaque, less than a minute. Transfer shrimp to plate as they finish cooking.

Step 3

Add Aromatics: Reduce heat to medium-low. Add minced garlic to now-empty skillet, cooking and stirring until fragrant and browning, less than a minute. Add diced tomatoes (including liquid in can) and cayenne to skillet. Stir to mix well. Simmer for about 5 minutes to thicken sauce a bit, stirring occasionally.

Step 4

Serve: Remove skillet from heat. Add shrimp back to skillet and stir with sauce. Top with feta cheese and chopped parsley. Serve (Note 2).
