What size sheet pan should I use?

A half-sheet pan, about 13 by 18 inches, fits a dinner for four.

How do I keep vegetables from getting soggy?

Spread them in one layer, use high heat and do not cover the pan.

One pan, one oven and very few dishes. Each of these dinners roasts a main and its vegetables together, timed so everything finishes at once.

Use a large, heavy rimmed baking sheet and give the food room; crowded pans steam instead of roasting.
