Chicken in parchment
Doreen Randal, rec.food.recipes
4 chicken breasts     Pound to an even thickness. Place each breast on a circle of baking parchment. Sprinkle with salt and pepper. Bake on a baking tray 10-12 minutes in a hot oven. Serve a packet to each person, cutting a cross in the top.
salt and pepper  
4 teaspoons wholegrain mustard     Spread with a thin layer of mustard, then cover with carrot, onion and thyme. Fold paper in half, seal edges well by folding them in a few times.
1/2 cup carrot julienned
1/2 onion thinly slice
1 teaspoon thyme  
Other good combinations are: fish with tomato slices, olives, oregano and zucchini; chicken with lemon, onion, lemon pepper and carrots.
Fish can easily be overcooked with this method.
