Stuffing

I am really in need of them, please give me some to do

One Watermelon.

Or: Noodles to your limit, then waiting for an hour and then Joghurt/Milk rice (there are those 1kg pots from Kaufland )

Pancakes. Do you prefer sweet or salty?

What was your last stuffing? Then I can adjust the proposals.

I once did 20 chicken nuggets, 2 big mac and 2 hamburgers

That sounds like you really prefer salty.

You could do pancakes with salty topping (cheese, onions, bacon,...)

Or if you like Döner: can you eat 2 of them?

If you just want to get full: Lots of noodles. Cheap and easy to chug down.

Or let's go for a combination: 2 BigMacs and then half a watermelon.
