Went to Brazilian restaurant "Picanha" in Burbank today with some friends, and had a tasty side disk of zucchini, which I normally don't like but was delicious. It consisted of:
zuchinni, sliced into 1/3" rounds (or slightly thicker than 1/4")
red onions, sliced & sauteed
scallions (green parts only)
a bit of oil
Warm, fresh and delicious! Zuchinni was tender but not soggy (still some tooth), red onions were soft and transparent, all rounded out by the nice sweet, salty flavor of the teriyaki sauce. Excellent.
