Try to minimize onion powder since onion isn’t a vegetable on your plan. You can have cilantro: in fact, you can have any herb and spice. Again, dehydrated onion is still onion and not considered a spice.If I don't have onions on my plan (I have shallots and leeks), is it ok to use onion powder or dried onion (for example dried onions are in everything bagel seasoning)? I also don't have cilantro on my plan, but I do have parsley, does that mean I can't use cilantro? I guess what I'm wondering is if there are any restrictions on herbs and spices.
