Are these recipes that you can still make without the onion? Or are onions an integral part to the recipe? I generally just omit them and proceed with the recipe. My hubby doesn't like them either and they generally give me heartburn.
Onion powder is generally the substitute for onion...it gives the same flavor but without the actual onions. Is it the taste he just can't stand, or the texture? With my husband, it's the texture he doesn't like.
