1Blend plantains, spinach, bread crumbs, cornmeal, mushrooms, olives, garlic, paprika, and oregano in a food processor until a moldable batter forms; mold into patties.
2Melt butter in a skillet over medium heat; pan-fry patties until golden brown, 6 to 8 minutes per side. Season with salt and pepper.

Cook's Note:
If for some reason the batter is a soupy texture, add more bread crumbs or cornmeal, 1 tablespoon at a time, until a thicker batter forms.
