I made this broccoli cheese quiche with a brown rice crust! I normally do crustless quiches because there is so much fat and unecessary-ness in the crust (although my family would disagree), but in adding the brown rice crust there's more texture and it stops being an egg casserole of sorts. Do this with any variety of quiche: ham, cheese, peppers, broccoli, potatoes, even sausage.
Here's where I got the recipe, but I would argue you could do with less cheese in the crust. This is a broccoli recipe, but try it with anything (and chop up the broccoli way more than I did here- the kids cried foul when they saw this, although they'll eat broccoli on its own just fine)
