There are a lot of variations of basic Thai Curry and this is one of the variations that we enjoy. Being  a vegetarian ,  I substitute tofu instead of meat. This is a quick version of the authentic Thai curry.
If you want to decrease your preparation time, you may want to buy a bag   Frozen Asian Stir Fry Vegetable Mix, available at Costo’s, Sam’s or any grocery store and stock a few cans coconut milk your pantry.
Grow your own lemon grass if you enjoy gardening. This link shows you- How to grow lemongrass.
