Baked Orzo, Broccoli, and Cheese

Quite a good dish, more or less a one-dish meal.

• The recipe is advertised to serve 4-6; I made a half recipe and it would have served 3, although we did have a starter.
• Any small pasta would work, but orzo was nice.
• Any strongish veg with texture, like cauliflower (or better, romanesco, for the color) or maybe cabbage would work as well.
• My jar of roasted bell peppers had both red and yellow ones, which was pretty.
• This might work well as a take-along casserole or as part of a buffet.
