I don't know about burger quiche but mushroom & spinach quiche sounds awesome!
Have you ever tried freezing it? DH makes up 2 quiches at the same time, bakes both. We'll have one for dinner while the other one cools on the counter. Then we slice it into wedges and package them for the freezer. It warms up nicely in the toaster oven.
