Leeks, shallots, onions and garlic combine to make a rich, delicious side dish. You can use jarred baby onions at step #3 and just not cook them for the additional 10 minutes as they are not frozen. This dish can be made a day ahead, just bring to room temperature before baking. One last thing, fresh grated Parmesan cheese is good on top along with the bread crumbs but is optional!
For extra-slushy Margaritas, freeze the drinks in the blender jar at least thirty minutes and up to one hour; stir, if necessary, before serving. Instead of using salt, coat the glass rims with superfine sugar: Run a lime wedge along the rims to moisten, then dip them into a shallow saucer of sugar.
