What other vegetables can I roast with asparagus?
Vegetable roasting times are somewhat depending on what kind of vegetable it is--broccoli is always going to take longer than spring peas.  But mostly, it is dependent on the size to which you cut them.

So cutting your other vegetables in smaller pieces will help.

Also, you can start, for example, carrots and broccoli, and give them a ten minute head start, then add the asparagus.
