This is a lovely way to cook any vegetables, it does not have to be limited to these vegetables so you fancy something else, use that instead.

Ingredients
400g baby carrots  
Brussels, the amount largely depends on how much you like them! 
100g frozen petit pois (no need to defrost) 
25g butter 
50ml boiling water 
1 tbsp sugar 
Salt 
Pepper

Method
Carefully and lightly peel the carrots and clean the top ensuring there is no dirt or grit. 

Cut the very bottom of the sprout off and remove 2 or 3 of the outer leaves. 

Put the water, butter, sugar and some salt into a large wok or frying pan and turn the heat to medium high.   When the butter has melted add the carrots and the sprouts and cook for 4-6 minutes shaking the pan from time to time. Add the peas and cook until a vibrant green - this is likely to take another 3-5 minutes. 

Your carrots should be tender but not be at all soft - same for the sprouts.
