It's a challenge, because sleep beats out every other choice including breakfast as far as teens go. Try to have things they can grab and go. When I'm organized, I try to make a tray of egg bites for them on Sunday for the week (mini-quiches in a cupcake pan), some spinach, some ham, etc., that they can grab from the refrigerator and take with them. And when I'm not, there's always some kind of granola bar/protein bar in the house they can grab
