Slice the cucumber into thin sticks about 2 inches long and 1/2 inch wide.
Cut the bell pepper in half, remove the ribs and seeds, and slice into thin pieces.
Cut the green onions in half the long way and cut into two-inch long pieces.
Cut the avocados in half, then peel and slice into thin pieces. Sprinkle with a little of the lemon juice to preserve their color if desired.
Toss the shrimp with the salt and pepper.
Heat the coconut oil in a large skillet over medium heat. When the pan is hot, add the garlic and the red pepper flake. Cook until the garlic smells fragrant and is just starting to brown.
Add the shrimp to the pan in a single layer. Don’t crowd the pan; if all the shrimp doesn’t fit in one layer, work in batches. Cook undisturbed on one side for about one to two minutes, until the shrimp begins to look opaque on the sides, then flip and cook for one to two minutes on the other side.
Squeeze the lemon juice over the shrimp and remove from the pan to a clean dish. Set aside while you make the sauce.
Lower the heat slightly and add the prepared Keto Chow. Stir to scrape up any bits of flavor stuck to the bottom of the pan. Cook until the sauce is heated through and lightly bubbling.
Add the shrimp to the sauce and heat until warmed through. Remove from heat immediately so they don’t overcook.
Divide the shrimp, sauce, and prepared vegetables between the eight lettuce leaves.
