This is one of my favorite quick weeknight dinners because it comes together in just half an hour. Grilled ahi tuna is incredibly lean and packed with omega 3s, which are fantastic for your heart and brain. The crisp, refreshing cucumber salad balances the rich fish perfectly, and the Asian inspired dressing with ginger, sesame, and lime brings everything to life. It tastes like restaurant food but honestly requires minimal effort and uses simple ingredients you probably have on hand already.

Instructions
- 1
Prepare the dressing by whisking together rice vinegar, lime juice, minced ginger, sesame oil, and soy sauce in a small bowl. Set aside.
Tip: Make the dressing while your grill heats to save time.
- 2
Pat the tuna steaks dry with paper towels and brush both sides lightly with olive oil. Season generously with sea salt, black pepper, and red chili flakes.
Tip: Dry tuna is key for achieving a perfect seared crust.
- 3
Heat your grill to high heat (around 450°F) and lightly oil the grates. Once smoking hot, place tuna steaks on the grill for 3-4 minutes per side for medium-rare doneness.
Tip: Don't move the tuna once it hits the grill—let it develop a golden crust.
- 4
While the tuna cooks, arrange sliced cucumber in a large serving bowl and pour the prepared dressing over it. Gently toss to coat and let sit for 2-3 minutes.
Tip: The cucumber will release moisture and absorb the flavors beautifully.
- 5
Remove the tuna from the grill and let rest for 2 minutes on a clean cutting board.
Tip: Resting allows the juices to redistribute, keeping the tuna moist inside.
- 6
Divide the cucumber salad among four plates. Top each with a tuna steak, scatter green onions and sesame seeds over the top, and drizzle any remaining dressing around the plate.
Tip: Serve immediately while the tuna is still warm for the best contrast with the cool cucumber.

My go to drink for summer gatherings is this refreshing Beergarita, and let me tell you, it's a total crowd pleaser.
