Serve up piping hot bowls of this rich and delicious vegetarian soup in under 40 minutes. Sweet potatoes are so filling and delightful as the base for the Tex-Mex-inspired soup. A quick puree of 2 cups and the whole pot is instantly more full with the thickened mixture. Corn adds a sweet note alongside the potatoes while chipotle chiles bring a mild heat to the dish. Black beans make this more hearty and a quick finish with cilantro and lime juice cools and brightens the flavours. Serve alongside a small green salad to amp your vegetable intake. For dinner or lunch, this soup is a year-round winner.
