Baked potatoes and oven baked sausages with bit of salad on the side
Baked potatoes with bowls for them to help themselves to: grated cheese, grated carrot, cooked and chopped bacon, chives, soured cream
Spag (or pasta) bolognaise. Although I do tend to cheat a bit (chop onions and garlic to fry with mince and some herbs but add both a jar of sauce and some chopped tomatoes). Freeze the leftovers for another day.
So I went with the Spanish chicken recipe on mumsnet. Went down v well except the addition of butter beans. But thank you for the other suggestions. Just seems like it's pasta, spag bol etc etc most evenings. I don't find it inspiring...but clearly can't tell them that!
