This is from the Induction list on this forum:

Other Vegetables
You can have one cup per day of these vegetables, in any combination if your salad portion does not exceed two cups. The following vegetables are slightly higher in carbohydrate content than the salad vegetables:

Artichoke, celery root, pumpkin, artichoke hearts, rhubarb, asparagus, chard, sauerkraut, bamboo shoots, bean sprouts, beet greens, broccoli, broccoli rabe, Brussels sprouts, cabbage (red, green, Savoy), cauliflower, chayote, collard greens, dandelion greens, eggplant, hearts of palm, kale, kohlrabi, leeks, okra, onion, scallions, snow peas, spaghetti squash, spinach, string or wax beans, summer squash, tomato, turnips, water chestnuts, zucchini


If you have a concern about onion then cut way back or go without, I have and they are still great. They really, really are great. I think I'll go and make them now.
