Ruby on Rails: How to populate an array using a form?

Question

[noob disclaimer] So I'm beginning with rails and I'm trying to have a form that adds toppings to a food order.
How can I make a form that for each checkbox 'ticked' the submission will add that topping to the array of ordered toppings to that food?

You're asking rather a lot so I think a couple of awesome railscasts are in order.
