"I hate mushrooms, but this recipe actually makes them edible. Being diabetic, I was trying to develop recipes that make the foods I hate edible and came up with this one. Both my wife (who loves mushrooms) and I like this stew."
Heat olive oil in a large pot over medium heat; cook and stir chicken until no longer pink, 5 to 10 minutes. Add onion and garlic; cook and stir until onion is slightly tender, about 4 minutes.
