Spicy Chicken Thai Soup
Most of the ingredients for this Thai-inspired soup can be found in the supermarket. The red curry paste is spicy, but by controlling the amount of paste you add, you can tailor this to your own threshold of pain.
The only exotic ingredient would be the fresh lemon grass. I've found most large grocery stores do carry it, but if not, you can substitute a few tablespoons of lemon zest.
