Rinse the shrimp under cold water and pat dry with paper towels.
In a bowl, combine honey, minced garlic, soy sauce, and olive oil. Stir in cornstarch if a thicker sauce is desired.
Heat olive oil in a large skillet over medium-high heat. Add shrimp in a single layer.
Sprinkle shrimp with salt and pepper. Cook for 2-3 minutes until shrimp start turning pink.
Pour honey garlic sauce over the shrimp and toss to coat evenly.
Lower heat and simmer for 3-5 minutes until shrimp are cooked through and sauce thickens.
Remove from heat and garnish with sliced green onions and sesame seeds if desired.
Serve immediately while warm.
