Creating Tuna Steaks with Creamy Garlic Sauce & Salad is quite straightforward. Just follow these easy steps:

1. Prepare the Tuna: Pat the tuna steaks dry with paper towels. Season both sides with salt and pepper.
2. Heat the Skillet: In a large skillet, heat 2 tablespoons of olive oil over medium-high heat until shimmering.
3. Cook the Tuna: Place the tuna steaks in the hot skillet. Cook for about 2-3 minutes per side, depending on your desired doneness (seared on the outside but still pink in the center is ideal). Remove from skillet and let rest.
4. Make the Creamy Garlic Sauce: In the same skillet, reduce the heat to medium. Add minced garlic to the skillet and sauté for about 30 seconds until fragrant.
5. Add Cream and Mustard: Pour in the heavy cream, stirring to combine. Add Dijon mustard and lemon juice, mixing well until the sauce is creamy and heated through. Season with salt and pepper.
6. Finish the Sauce: Stir in the chopped parsley and remove from heat.
7. Prepare the Salad: In a large bowl, combine mixed greens, cherry tomatoes, cucumber, and red onion. Toss with your favorite dressing, or simply drizzle with olive oil and lemon juice.
8. Slice the Tuna: Slice the tuna steaks against the grain into thick pieces for serving.
9. Plate the Dish: Serve the sliced tuna steaks on a plate, drizzled with creamy garlic sauce. Add a generous portion of the fresh salad on the side.
10. Garnish: Optionally, garnish with lemon wedges for an extra touch of zest.
