Step 1:

• Prepare the tomato basil relish.
• In a medium bowl, combine the cherry tomatoes, basil leaves, red onion, and garlic.
• Drizzle with balsamic vinegar and olive oil, then season with salt and pepper to taste.
• Mix well and set aside to allow the flavors to meld.

Step 2:

• Season the tilapia fillets with salt and pepper on both sides.
• Heat 2 tablespoons of olive oil in a large skillet over medium-high heat.

Step 3:

• Once the oil is hot, add the tilapia fillets to the skillet.
• Cook for about 3-4 minutes on each side, or until the fish is opaque and flakes easily with a fork.
• Add lemon slices to the skillet during the last minute of cooking to infuse the fish with a subtle citrus flavor.

Step 4:

• Transfer the cooked tilapia fillets to a serving platter.
• Spoon the tomato basil relish over the top of each fillet.
• Garnish with additional fresh basil leaves if desired.
• Serve immediately with your choice of side dishes.
