Our versions of eating 'challenges' are invariably English breakfasts or fish and chips. Just the grease that the fats want. The only one I've done is a Harry ramsdon fish and chip challenge. I got the certificate anyway despite leaving the chips (you just had to finish the big big piece of battered fish) [so everyone pretty much gets a 'medal' as they eat the fish first normally anyway despite the rule on the chips not being posted]
