Thinking about it now, not sure if you can get everything in the UK you'd need, but the meatballs I've done are the following, sounds weird, but really, really good.
I use frozen meatballs, but you could make your own if you had the time. Frozen ones are much easier
Mix up one jar of pineapple ice cream topping or pineapple preserves
one bottle of bbq sauce, whatever is your fav
1 cup brown sugar
Pour over meatballs and cook in slow cooker until heated through. The longer they cook, the better they get.
They end up with a nice tangy flavor and kids usually love them, adults too.
Spinach and artichoke is so yummy. Great with tortilla chips by the way, especially if you heat the chips up just a bit in the oven.
