This creamy mushroom pasta makes a healthy, super-satisfying dinner for two at just over £1 per portion. Dr Rupy uses silken tofu to give the sauce a wonderful creaminess and extra protein.

Add the mushrooms and noodles and simmer for 3–4 minutes until the noodles are cooked. Stir in the bok choi and lime juice and season with salt and pepper, if needed. Simmer for a further 2 minutes.
