My mum's recipe - it's become a staple for us. I add a lot of stuff to it, depending on what is in the house. Worchestershire, onion, celery, corn, carrot, mustard... whatever. And yes, they are very kid-friendly. Jamie and I often eat them when he has something to get to (Beavers, swimming lessons etc) and Will's at work. We usually add steamed veg, maybe some oven chips ... I nuke them from frozen for about a minute and a half each.
"Quick to make, easy to freeze, good to eat (I tested them already!) They would also be very kid-friendly - if I was making them just for adults I'd spice them up a bit more.
In large bowl mix:
1 cup ketchup
3 tbsp brown sugar
1 tsp ground mustard
Remove 1/2 cup of ketchup mixture and reserve for topping.
Add to large bowl:
2 lightly beaten eggs
3 cups of cereal - measured and then crushed (I used rice crispies)
3 tsp onion powder
1/2 tsp salt
1/2 tsp garlic powder
1/2 tsp pepper
Mix all of that and let stand for five minutes so the crumbs absorb most of the moisture.
Crumble 1 1/2 kilos of lean ground beef over the crumb mixture and mix well.
Press meat mixture into 18 muffin cups (about 1/3 of a cup of meat per muffin) and bake at 375 for 20 minutes.
Spoon or brush reserved ketchup mix on top and bake for another 10 minutes or until you're sure they're cooked through.
Cool, freeze on a cookie sheet, pack frozen meat muffins into freezer container.
To serve - thaw in the fridge and bake at 350 for about 30 minutes or nuke em for 1 minute."
