Sauteed Portobellos and Spinach

This recipe is very easy. Portobellos are the only necessarily fresh ingredient. I would use a lot more red wine and a lot more Parmesan if making it again; both of those flavors got lost, or else the Costco portobellos are just extra-strong.

Speaking of Costco, the produce there isn't so great. We picked up four big portobello caps ($4.49), 12 great big Gala apples ($4.99), five lovely avocados ($4.99), a big double hand of bananas ($1.29), ten pounds of large yellow onions ($3.29), and an awful lot of garlic ($3.29). So far the avocados are quite tasty, but the apples were disappointing and the portobellos had kind of a fishy smell. The first bag of onions I picked up had suffered a serious mold attack; I hope the one I bought doesn't also succumb. Garlic's tough to wreck. We'll see. The bananas aren't ripe yet (but struggling along in a paper bag with an apple). In the future I think I'll stick to Trader Joe's (which has a lot of cheap decent organic produce), and of course our trusty box.
