In a saucepan with a tight fitting lid, bring chicken broth to a boil.
Stir in grits & pinch of salt. Reduce heat to low & cover. Simmer for twenty minutes, stirring occasionally.
While grits are cooking, crumble and brown breakfast sausage. Drain fat.
When grits are finished cooking, stir in sausage & shredded cheese. Taste and salt if necessary. Usually the chicken broth & sausage adds enough.
Pour grits into a greased 13X9 baking dish.
Let dish rest at room temp for about half an hour then store in refrigerator. Chill until firm - at least 2 hours. I prefer to make this the day ahead.
When ready to serve, cut grit cakes into squares, dip in flour if you'd like and fry in 1/2" deep cooking oil. Lightly brown on both sides. Alternatively, you can bake on a greased cookie sheet: dot tops with butter and bake at 400° for about 25 minutes. Have no time - go ahead and throw it in the microwave.
Can be eaten alone or served with maple syrup, sour cream or an egg on top.
Notes
Please note that I haven't added any salt, pepper or seasonings. Breakfast sausage is usually heavily salted & seasoned (as chicken broth salted). Please taste an adjust seasoning to your preference.
