First put some yogurt between two pieces of toast and with honey.To add some vitamin into the sandwich,i suggest to cut up the apple into pieces and sandwich them between the toasts.Oh,remember.You need to peel the apple before cutting it into pieces because it would be cleaner and more tasteful.But,personally, I prefer the apple having the peel.It all depend on your favor .If you want the sandwich to be spicy,you probably could add a slice of turkey with some onions on it.Ok,a delicious sandwich is almost made.Finally,you need to slice the toasts into two triangles.Sandwich is a kind of food that are very convenient for us to carry and it is quite easy to make a tasteful sandwich.I truly hope ypu can enjoy it,my friend
