In the bowl of a food processor or blender, place garlic, capers, olives, salt, and pepper. Blend until it becomes a paste.
Squeeze lemons over tuna. Smear garlic paste on both sides of each tuna steak. Heat olive oil in a sauté pan over medium heat. When oil is shimmering, place tuna in the pan; reduce heat to low. Cook for 3 minutes on each side for medium doneness.
Keep an eye on the garlic paste to make sure it doesn’t burn. Serve with Orzo with Feta and Basil.
