Don't worry, it's super easy!.
1. Go the the store and buy a fresh cucumber, any bread of your choice, and a spread and condiments to put on the sandwich. I like to use whole-grain wheat bread, mayonnaise, chives, and dill.
2. Put your spread on both pieces of the bread. Cut your cucumber into thin or medium slices. I find usually six is good.
3. Sprinkle some chives and dill on the cucumber.
4. Close your sandwich. If you want, you can toast it until it's to your liking!
5. Serve with your favorite side---I usually do apple slices and Greek Yogurt.
6. Enjoy! :D
