Watercress Sauce

This sauce is delicious with meat, fish or poultry. Make it just before serving.

Ingredients:

2 bunches watercress
13 ounces (400 g) low-fat natural yogurt
Juice of 1 lemon
2 cloves garlic
Ground black pepper

Method:

1. Steam watercress for 1 minute, or microwave on HIGH for 15 seconds.
2. Blend watercress with all other ingredients in a food processor or blender to produce a green speckled sauce. This sauce retains its bright green color for about one hour.

Hint: Substitute one bunch of English spinach if watercress is not available.
