How to Make It
Cook the grits according to the package directions. Stir in the Cheddar.
Meanwhile, cook the bacon in a large skillet over medium heat until crisp, 6 to 8 minutes. Transfer to a paper towel–lined plate.
Add the shrimp and tomatoes to the skillet and cook, tossing occasionally, until the shrimp are opaque throughout, 3 to 5 minutes.
Stir in the scallions and the bacon and serve over the grits.
