No luck searching for the "tomato-sweet potato-peanut stew" thing - when I didn't find it by following the food tag* I figured the best option was searching for peanut as the least common ingredient, but zilch (well a couple of references to things that involved peanuts, but none with sweet potatoes or tomatoes). OTOH have grabbed a mushroom stroganoff recipe as I've a load of mushrooms to use up :)

*That's a lot of recipes!
