You will probably have a bit more dressing than you need for two salads, but some people might want more or less. If you have a bit left over, serve it with some fresh bread!
*To roast a red pepper without heating up the oven or a grill: I stole this method from Smitten Kitchen, but it works really well when you want a little char flavor without a bunch of effort. Unfortunately it only works if you have a gas stove.
Turn on a burner and rest the washed and dried pepper on the tines over the flame. Turn with tongs as each side chars.
