Follow the package instructions to prepare the grits but for what ever amount of water it calls for, cut that in half and use milk for the other half.
Get your grits going, season with salt and pepper to taste, and stir often to make nice and creamy grits. When the grits are done, add in Cheddar to your liking and stir in, set aside but keep warm.
Get everything else prepped, measured, and set out and ready to go, this will come together quickly.
In a large non stick pan on medium high heat, heat the oil and butter. When hot, add the ham and saute until crispy. Add the onion and bell pepper and saute until the onion is translucent then add the garlic and cook for 1 minute.
Add the shrimp and saute for 1 to 2 minutes or until all the shrimp are pink. Pink shrimp are tender, over cooked shrimp are tough. Remove the shrimp when pink and set aside.
Stir in the white wine and let it reduce. When it has reduced, slowly stir in the cream, season with salt and pepper, and if you used sausage or bacon, season to taste with Cajun seasoning. Let sauce reduce to thicken.
Divide the grits between two plates, divide the shrimp onto the grits, pour sauce equally over each plate, top each plate with chopped spring onion greens. Serve.
