1 can cream of mushroom soup
1 soup can water
1 can tuna, drained
1 can peas, including liquid
1 sm. can pimiento, including liquid (optional)
1 pkg. macaroni and cheese dinner

Mix all ingredients in 2-quart baking dish and microwave, covered for 12 minutes on High. Leave cover on the casserole and let stand AT LEAST 15 MINUTES before serving, so macaroni will reconstitute and will become tender.
