Whisk the honey, soy sauce, garlic, and ginger (if using) together in a medium bowl.
Place shrimp in a large zipped-top bag or tupperware. Pour 1/2 of the marinade mixture on top, give it all a shake or stir, then allow shrimp to marinate in the refrigerator for 15 minutes or for up to 8-12 hours. Cover and refrigerate the rest of the marinade for step 3. (Time-saving tip: while the shrimp is marinating, I steamed broccoli and microwaved some quick brown rice.)
Heat olive oil in a skillet over medium-high heat. Place shrimp in the skillet. (Discard used marinade2.) Cook shrimp on one side until no longer pink– about 45 seconds– then flip shrimp over. Pour in remaining marinade and cook it all until shrimp is cooked through, about 1 minute more.
Serve shrimp with cooked marinade sauce and a garnish of green onion. The sauce is excellent on brown rice and steamed veggies on the side.
You can remove the tail or leave it on. Whatever’s easiest!
Using leftover marinade is a debated topic. While you could boil it to rid any contamination, the flavor could possibly change. But do what you’d like. Usually I just make a little extra (like we do here) to use as the sauce.
