You can plant them and it takes 2 years to produce normal garlic for all but the largest bulbils. (the pea sized bulbils of some garlic can produce in one year).
You can lightly crush them with the flat blade of a knife and they will then squeeze through the garlic press. For any long cooking (stew etc) they can be used, skins and all, and the skin will cook soft and not be a problem in a stew. You can add to a bouquet garni which is a herb mixture in a little muslin sack and which gets taken out before serving.
You can plant them up for green garlic. Densely planted now they will give you chive like plants in spring that have many uses in the kitchen for a milder garlic flavour.
