Cooking always adds quantities. The type of meal cooked only affects the number of "stacks" of food combined. The quantities of all the cooked stacks are added, and the sum is the quantity of the stack of prepared meals.
If you're cooking up a bunch of stacks of Horse Meat[5], for example, an easy meal combines two stacks of five into a single stack of ten meals, and a lavish meal combines four stacks of five into a single stack of twenty meals. You still have the same number of food-units, but you've consolidated them into smaller groups.
So cooking easy meals is the most efficient way to train your cooks (since they have more cooking jobs to process the same amount of ingredients), and cooking lavish meals is the most efficient way to manage your food stockpile space (since you have fewer stacks of prepared meals in the end, and large stacks of meals are often too big to be stashed in barrels with each other.)
Note that cooking doesn't produce any extra item-quantity-units, but it can produce more edible food if you are cooking ingredients that aren't edible raw, like syrup, flour, and quarry bush leaves. When I got inattentive with one fort and let food supplies run out (oops!), my dwarves were saved from catastrophe by cooking biscuits out of spare seeds.
