Crush the tennis biscuits, add adequate amount of butter so that the biscuit can form a base for the tart. Use a quiche dish.

Pour the yoghurt and condensed milk together. Stir vigorously, and pour into the biscuit base quiche dish.

Put in microwave for 1-2 minutes or until it just forms tiny bubbles on the surface. Be careful not to over heat the tart or it will curdle!

Place tart in fridge. Setting can take from 30 minutes to an hour. It must have a soft yet slightly firm texture. Test it like you would test jelly.

Hint! You can use low fat yoghurt as well! And you can make a half-half type, just divide using a folded piece of tin foil. Becareful using tin foil in the microwave by keep checking every 30 seconds when microwaving.
