I am trying to find a change a recipe for a vegetarian stew that can be slow cooked. It is called vegetarian cholent which is served for Saturday lunch. However, I need help modifying this recipe. The general recipe includes: onion garlic potatos barley beans celery some spices like rosemary, tarragon, and cumin. All of the recipes I found include onion soup mix. I would like to find a way to use a fresh substitute for the onion soup mix.
