As much as I admire fancy stovetops with extra burners, I really don't get it. I have five burners, one more than the fully functional stove of my youth, and after ten years, I can count on one hand the number of times I've used all five at once. I rarely use more than two, and on any given weeknight, one will do it.
See, I have a collection of completely no-cook side dishes that can easily be served with any entree. They are on regular rotation in my house, and I love that I can whip them up in the minutes before putting dinner on the table.
