In order to bulk up the leftovers, lots of asparagus was added to the mix. You simply can not have too much asparagus. In fact, the more the better in my books.
I also cleaned out the Portabella cap, giving myself much more room for tasty filling. I threw my leftover veggie quinoa into the pan with some water just to rejuvenate it a bit, then added the diced asparagus to the mix.
While the vegetable quinoa was cooking, I brushed the Portabella cap with olive oil and baked on 400F for about 10 minutes (or until soft). Once soft, I pulled the cap and filled it with quinoa. I crumbled some goat cheese, dressed a few smaller mushrooms with goat cheese as a side as well (why not?!) and put these back in the oven until the cheese turned soft.
