Ok, can do loads from that.
Chicken:
Put some chicken thighs, potatoes cut into wedges, whole, unpeeled cloves of garlic (I do 2 per thigh as a rule) into a shallow dish/roasting tray. Season, drizzle of olive oil and sprinkle of thyme or oregano. 190c for about 40 mins. Serve with a salad in summer or french beans or something in the cooler months. It's sort of self saucing, and nice with some crusty bead to mop up juices.
Waitrose own brand teriyaki sauce is, IMO, the best. Marinade some wings, legs or thighs in some and then shove in oven or under grill for as long as needed. Serve with sticky rice and some stir fry pak choi/baby corn.
Lamb:
Lamb steaks, cut into bite size bits. Make a marinade with olive oil, crushed garlic, salt, splash of lemon juice and the grated rind, and chopped rosemary. Leave to marinade for a couple of hours, then skewer, alternating with (if they like) anything like mushrooms, courgettes, cherry toms etc. grill and serve with pita/in wraps with kebab style bits and bobs.
Make a yoghurt dip to go with it (this is also nice with the first chicken recipe above). Greek yog, grated clove of garlic, generous pinch of dried mint, small pinch of oregano and seasoning.
Beef:
Stroganoff sort of thing. Thinly slice some rump or sirloin. Chop one medium onion and sauté that in some olive oil. Add in the steak and when cooked, stir in a teaspoon of tom purée. Cook through for one min and then add a good dollop of creme frâiche. If they like mushrooms, then Finely sliced and flung in with steak. Rice to serve.
Salad: we have this quite a lot at the mo.
Roughly chop tomatoes and some cucumber. Pop into a decent sized bowl and then sprinkle fairly generously with Malden salt. Chop/tear up a romaine or cos lettuce and put on top of the toms/cucumber. Finely chop some spring onions and add in.
Leave to one side. Finely slice some chicken breast and put in a small bowl with a splash of olive oil. Sprinkle over some Schwartz season all (stay with me!) and make sure all the chicken is coated nicely. Heat a pan up and then fry off some lardons. When crispy chuck on top of the salad. Then cook the chicken in the same pan, tipping the lot into the salad when done.
Next a squeeze of lemon juice and splash of olive oil and then give the salad a good mix. Delicious and despite how much effort it looks, it's really really quick and easy.
