Noodles with Tofu, Mushrooms and Watercress in Blackbean Sauce (v)

I love watercress and think it's highly underused as a cooked vegetable. Use it like spinach but appreciate the peppery bite of it more than metallic spinach. This was very quick to throw together and tasted lovely.

For one hungry person you need:
1 bundle noodles
1/2 packet watercress
1 onion, sliced
3-4 mushrooms, sliced
1/2 jar waitrose cooks ingredients blackbean sauce
1 marinated tofu steak, cut into bite sized pieces
1 tsp vegetable oil

Cook/soak the noodles and leave to drain. Fry the onion and mushrooms in the oil for 4-5 mins. Add the tofu pieces and cook for a further 5 mins till lightly browned. Add the blackbean sauce (and a little extra water to get it all out of the jar). Heat through. Turn off the heat and add the watercress. Allow to wilt. Serve on top of the noodles and scoff. Yummy.
