OP
Do you have a slow cooker?
Do the portions have skin on?
If the portions have skin on then this is tasty and easy.
Buy some thyme - if you can't find fresh then dried will do. Buy some lemon juice, or a lemon.
Put the defrosted chicken in an ovenproof dish or oven tray.
If you have bought a lemon then juice it. If you have bought lemon juice then sprinkle it over the chicken - just as you would put binegar on chips, sprinkle over dried thyme or place sprigs of fresh over the chicken.
At this point you can add any spices you like, or salt and pepper, I tend to just add a little pepper.
Put in the oven (on full power) and cook for 20 - 30 mins. Check after 20, if you put a squewer or knife intot he chicken juices will come out, if they are clear the chicken is cooked.
If they are skinless, then buy a tin of campels condensed mushroom soup, some mushrooms and a tub of creme fraiche.
Slice the mushrooms.
Put the defrosted chicken in the slow cooker if you have one (and it is a small one) or into a large pan.
Add the soup, straight from the can, add the mushrooms and creme fraiche. If you have a slow cooker then switch it on, if you are using a pan bring it to the boil and then simmer for 20 - 30 mins.
