Drain the liquid from the canned green beans and put the green beans in a casserole dish. Add the cream of mushroom soup to the green beans and thoroughly mix together. Lastly, add the desired amount of slivered almonds to the top of the green bean mixture.
Then, microwave the casserole for 5-7 minutes. Before serving, mix the almonds on top into the casserole right before serving. Enjoy!
