One thing dieters can take advantage of on yom tov is SOUP. Unlike shabbos, on yom tov you can warm up (or cook up) some soup to fill you up. Here is an old favorate of mine which is very adaptable.
Delicious Vegetable Soup
One can (28 ounces) crushed tomatoes, no sugar added
2 cans water (58 ounces)
three onions, cut up
4-6 stalks celery, cut up
3 beef or chicken boullion
1 bag (20 ounces) frozen carrots
1 bag (20 ounces) frozen string beans
1 bag (20 ounces) frozen cauliflower
1 large head of cabbage, cut up
combine all ingredients in a VERY LARGE pot. Season with your favorate seasonings. cook until celery is fork tender, about 1-1 1/2 hours. I like to take part of it and blend and then put back into pot. freezed well for succos too, enjoy!
Hey, how about low cal. section, YW??
Soup is a great diet aid, as long as it is not creamed or thickened with a starch. The idea of blending part and adding it back is a good one, it will thicken the soup to a creamier consistency. The addition of chicken pieces and/or giblets will make it heartier.
Steer clear of trying to be too great a “tzaddik” in eating challah and honey. A kazayis is enough (THAT is my personal Waterloo, that and my home-baked honey cake).
