Emma's Beef

This recipe is from the wonderful Emma over at http://www.e-ddoesit.com/ - she's amazing at making great food from simple ingredients :) Amongst many other things too! I got this recipe from her blog, and I adapted it to suit what I had in the fridge at the time. It has become known fondly in our house as "Emma's Beef" in honour of the creator haha :D

I've made this using sour cream, creme fraiche or cream cheese, or a combination of any of those, depending on what's in the fridge. Usually, I'll use Lidl's light cream cheese, it's got I think 4% fat and is only 70-odd cents for a pack. (or Tesco's version of same, it's more expensive but because of their price promise you always get a voucher for the difference anyway).

Emma's Beef
Ingredients
2 onions, chopped
10 mushrooms, sliced
4 cloves of garlic, minced
2 green peppers, sliced
2 tbsp wholegrain mustard
250 g sour cream, creme fraiche or cream cheese
500 g pack of beef strips (stirfry beef steak)
3 tbsp balsamic vinegar
squeeze of lemon juice
Enough tagliatelle for 4 people

Method

1. Put the beef in a bowl with the vinegar and lemon juice and season with salt and pepper. Mix well to coat with marinade. Set aside and leave to marinate a bit. You can use this time following to chop your veg.
2. Heat a tbsp of olive oil/rapeseed oil in a large frying pan. Fry onions, mushrooms, garlic and peppers for 5-6 minutes until softened. Cook pasta.
3. Add the beef and marinade to the pan. Fry for about 4-5 minutes.
4. Add in the sour cream (or alternative) and the mustard. Mix well and bring to a simmer. 
5. Serve with tagliatelle, crusty bread and a big glass of red wine :)
