Add the onion, celery, and, if using, bell pepper. Lower the heat to sauté, stirring occasionally.
*High smoke point oils include avocado (refined), almond, corn, canola, grapeseed, peanut, safflower, sesame, and sunflower.
**Use these substitutions call me if you were not nightshade-free.
Like it Spicy?
Feel free to add a teaspoon or two of cumin for additional flavor. If you enjoy it hot, add gluten free taco seasoning (McCormick makes a gluten free version), chili powder, or even gluten free hot sauce or chipotle sauce.
Low-Histamine?
Beef broth or base purchased in stores are not low-histamine, but if you watch other low-histamine foods for the day or week, you can probably have a bowl now and again.
I read a recipe for bone broth that is low-histamine, but you have to get the bones from a farm/neighbor. However, this recipe can be made without the beef base. You just neeed to add more spices like 1/2 teaspoon ground thyme and maybe 2 teaspoons ground cumin.
