Boil water in a 3 quart pot over high heat then stir in the grits. Cook for 3-4 minutes or until the grits begin to thicken, then remove from the heat.
Stir in parmesan cheese, butter, ½ teaspoon of salt and ½ teaspoon of pepper.
While the grits are cooking, fry the bacon in a skillet over medium heat. Cook until crispy then remove the bacon from the pan and set aside for later. Do not clean out the grease.
Add the shrimp, remaining salt and pepper and paprika to the pan then cook for about 3 minutes or until the shrimp are pink throughout and just beginning to curl.
Pour in the lemon juice and cook for another 2-3 minutes, then remove the pan from the heat and stir in the bacon.
Spoon some grits into a serving bowl and top with some shrimp. Garnish freshly chopped parsley if desired.
Notes
The grits are best eaten the day they are made. However, the shrimp and bacon will keep fresh for up to three days. Store the shrimp in an airtight container in the fridge.
