Answer 2

Create the a single Scanner in your class/main method and pass that scanner to your other methods:

...
static void main(String[] args)
{
Scanner input = new Scanner(System.in);

....
// Didn't check the names of each function..

MainMeal(input);
Salad(input);
Dessert(input);
....

input.close();
}
....
