To make the pico de gallo, place all ingredients in a bowl and mix. Refrigerate until ready to use.
To cook the pork, preheat oven to 375'F.
In a skillet sear the pork to achieve a golden color on all sides.
Place pork in a shallow baking pan and cook following the package instructions.
Remove pork from the oven and cover it so it can rest for about 5 minutes.
While the pork is resting cook the grits.
In a saucepan place water, milk, and salt then bring to a boil. Immediately add the grits and stir constantly for about 5 minutes. Next add the cheese and stir vigorously to incorporate it into the mixture.
Finally, serve by placing a mound of grits in a bowl, topped with the sliced pork, a spoonful of pico de gallo and avocados.
