[Correction: Yes, I finally realized that I had included a non-vegetarian soup in my suggestions. Sorry about that! I've removed the link.]
[Part one, a general discussion of ways to make your cooking more efficient, can be found here.]
When you're thinking about quick meals, keep in mind that salad or leftover soup (including frozen portions) can help round out a meal, as can fruit and cheese at the end of the meal. Salads can include protein (cheese, hard-cooked eggs), as can creamed soups, or they can simply complement your main course.
The links below take you to quick (some quicker than others) recipes on this blog. The tabouli and lentil salads can definitely serve as a main course. Most salads (although not the fattoush) can be made at least a day ahead.
The last and final part of this series on quick(er) vegetarian dishes will feature not so much recipes as suggestions for very speedy dishes and/or for dressing up leftovers or staples like rice and pasta.
