sides with brisket

My boyfriends brother is visiting from out-of-town and has requested brisket. I will be braising in beer/chili sauce/lots of onions/garlic, refrigerating overnight, slicing, and rewarming in bbq.

Consequently, I made this same entree last time he visited; it lingers in his mind. :) Anyway, Id like to change up the sides but lack inspiration. Last time we had roasted cauliflower and sauteed corn with peppers, chilis, and red onion.

For an appetizer we are having hot garlicky artichoke dip (which I found on CH and have made many times to rave reviews) and dessert will be a rum cake that is "marinating" as I type.

The only items not liked are "chunky tomatoes" and mushrooms. Also, we are urban, so no grill available. Thanks for any and all suggestions.
