Roasted asparagus and roasted onions are always a winning combination, but this balsamic orange drizzle puts them over the top! I used a sweet onion inplace of a purple onion, but otherwise, I made this as written and loved it. I may try to roast the veggies IN the sauce next time to get a more glaze effect. Thanx for posting.
I liked the taste of the dressing on top of the asparagus and onions. I needed to cook the onions just a few minutes more. For the dressing, I omitted the salt and sugar. Another time I'll reduce the amount of balsamic vinegar. Thanks Oolala :) Made for Alphabet chef tag game.
