It's pretty easy. The salad is just:
A bunch of leafy greens like Feld Salad, which kind of looks like Cress.
Grilled chicken with a bit of salt to season.
Fresh mango pieces.
I recommend organic ingredients.
The mango dressing is a bit more complex but you don't have to puree or anything, just pour and mix:
3 spoons plain yogurt
Dash of cream
1 tbs mango chutney
1 tsp curry powder
2 tbs OJ
1 tbs lemon juice
2 tbs sherry vinegar, or 1 tbs apple vinegar and 1 tsp sherry
1 diced red chili
a dash or two of ginger (fresh is best but I never bother)
1 tbs sesame oil
2 tbs peanut oil
optional: 1/4 onion, diced small
Now taste it and add anything you think it still needs, like salt or maybe a dash of sugar.
You can also buy mango dressing at TJs but fresh is better.
