In a skillet, cook bacon over medium heat until crispy. Remove bacon and set aside, leaving the grease in the pan.
In a saucepan, bring water to a boil. Stir in the grits and reduce the heat to low. Cook, stirring occasionally, for 15-20 minutes until thick.
Stir half-and-half, salt, and pepper into the grits. Keep warm.
Add the shrimp to the reserved bacon drippings and cook until pink and opaque.
Remove skillet from heat. Stir in lemon juice, hot sauce, and cooked bacon.
Serve shrimp over warm grits. Sprinkle with green onions. Enjoy!
