Preheat oven to 350. Brown sausage, onions and peppers until sausage is no longer pink. Add can of Rotels, Cajun seasoning and oregano and let simmer for 10 minutes.
Next add the 2 cans of black-eyed peas, cooked rice and cream of chicken soup to meat mixture. Put entire mixture in 2 quart casserole dish. Top with one cup of cheddar cheese. Cook in preheated oven for 25 minutes.
Notes
The canned black-eyed peas that we buy, are very thick and not in a lot of juice, so we don't drain them. You can certainly rinse and drain the peas if you like.
