Dont know for sure where recipe came from, but Im thinking it came from old church recipe book, something like Mt. Zion Baptist Church.Tried it, really liked it, but I love tomatoes. Hope someone else enjoys as much as I have.
Heat oven to 350. Lightly grease a shallow 2 qt. baking dish. Bring 2 cups water and the milk to a boil in large saucepan.
Add salt and then slowly add grits and return to boil, stirring constantly for 1 minute. Reduce heat, cover and cook 3 minutes. Add stick of butter, stir till melted; Cover & cook 3-5 minutes, until thick and creamy. Remove from heat and set aside.
Melt remaining 1 T. butter in skillet, add scallions and saute 1 minute, add to grits along with the garlic and 1 1/2 cups cheese. Stir till cheese melts.
Add tomatoes, mix well. Pour into baking dish. Bake 40 minutes, sprinkling with rest of cheese last 5 minutes. Bake at 350-375 till bubbly and lightly browned and knife comes out clean.
