One of the main challenges with vegetarian food is making sure a dinner feels hearty enough. Here, you've got an entire half of an acorn squash per serving, stuffed with mushrooms, spinach, bread cubes, and goat cheese. In other words, it’s not shy on flavor, and the portion feels, well, like dinner. Pro tip: If the squash halves seem unsteady on the baking sheet, you can slice off a little of the outside skin to make a flat base. Serve with a crisp white wine like dry Riesling or Vinho Verde.
