Sauté the onion, garlic, and mushrooms in olive oil (or broth) until softened.
Dredge your chosen protein (lean chicken, turkey, or tofu) in whole wheat flour or almond flour. Brown in a little olive oil or broth.
Add low-sodium broth, apple cider vinegar, Worcestershire sauce (optional), and spices. Simmer with the carrots until tender.
Add potatoes and simmer further. Add the sautéed mushrooms and vegetables back into the pan and simmer until everything is tender.
If the stew is too thick, add more broth; if too thin, thicken with cornstarch slurry.
Serve with a side of steamed veggies or a light whole grain bread.
