Right, here's a quickie!

What you need (for 4 people):

8 pieces of chicken
2 garlic cloves
salt, pepper, olive oil, butter
200 gr. leaks
200 gr. mushrooms
½ bottle dry white wine
½ pint double cream
1 handful tarragon
2 teaspoons Dijon mustard
1 lemon

How you do it:

Joint a chicken into 8 pieces (or just buy chicken pieces) and season them rubbing their skin with salt, pepper, and garlic. Brown in oil and butter in a large pan.
Add chopped leaks, more garlic and quartered mushrooms.

When chicken and vegetables are browned, deglaze the pan with the wine, stirring in any burnt bits on bottom of pan. Boil off the alcohol.
Add the cream, a good handful of chopped tarragon, 2 teaspoons of Dijon mustard, and a squeeze of lemon juice. Simmer for 20/30 minutes until the chicken is cooked through.

Adjust seasoning and serve with sautéed potatoes or buttered noodles and whatever vegetable you prefer (French beans go well).
