I made the sauce yesterday evening and roasted the asparagus this morning before going into work. After a quick taste, I decided that sesame oil and wasabi goes extremely well with asparagus.
When I arrived at the office, there were only a half-dozen or so people in and I wondered if I'd made too much as I put out the two plates with a pile of asparagus on each.
I needn't have worried. By lunchtime, there were only a few stalks left and everyone said how much they enjoyed it.
