Notes
Storage suggestions: This recipe reheats well (I just warm them in the microwave). Leftovers keep well, covered and refrigerated, for about 4 days.
Change it up: You can cook leftover vegetables with the garlic, before adding the spinach. You could also use chopped kale, chard or collard greens instead of the spinach—those will just need a little more time in the skillet to soften.
*Parmesan note: Most Parmesans are not technically vegetarian (they contain animal rennet), but Whole Foods 365 and BelGioioso brands offer vegetarian Parmesan cheese.
