Low-Fat Caesar salad dressing from "Cook Yourself Thin"

I haven't made this yet, but wanted to write it down before I forget. I caught this new show last week called "Cook Yourself Thin". It's a UK show featuring this 4 girls who are quite slim, showing you how to eat foods that are lower in calories. It was quite easy to watch, actually. The foods they cooked were more on the English side, but they made it look simple and the show had a qualitative side to it since they showed how they measured caloric content, etc.

Anyway, one of the recipes was for a chicken caesar salad. Here is the recipe:

Healthy chicken caesar salad recipe

Serves 2
Ready in 30 minutes

Ingredients
The salad
2 boneless free-range chicken breasts, take the skin off for extra skinniness
Olive oil spray
Salt and freshly ground black pepper
2 slices of soya and linseed bread
3 little gem lettuces 6 fresh anchovy fillets (optional)

The dressing
1 small clove of garlic, peeled and grated
2 anchovy fillets in olive oil from a jar
Salt and ground white pepper
3 tablespoons 0% fat Greek yoghurt
A squeeze of lemon juice
20g freshly grated parmesan (with a microplane)

I'll probably skip the chicken breast bit but they made the dressing sound delish. If it's low fat, why not right? I love caesar salad!
