Boil potatoes in salted water for 10 minutes. Then, add corn and boil for another 10-15 minutes until potatoes and corn are tender. Check by piercing with a fork.
After putting potatoes in to boil, season shrimp with salt, pepper, and cilantro-lime seasoning.
Melt 1 tbsp butter in a skillet and add garlic. Sauté for 1 minute then add shrimp. Cook on both sides until pink, about 5 minutes..
Then add remaining butter, fresh-diced cilantro, and lime juice to create cilantro-lime sauce. Stir shrimp in sauce to coat.
Plate shrimp, spoon some sauce over the top and sprinkle with diced cilantro. Plate potatoes and corn (with butter and salt, if desired).
