i got hungry once, but there wasn't much stock or many leftovers in our house, just a few veggies in a big bowl and some condiments, i even tried eating cucumber and raw garlic with salt once because i was really hungry lol i had no choice, plus i didn't have any extra money to buy snacks outside lol 
thats the only thing i really remember that i did few weeks ago but i actually tried a different kinds of food combination , i just forgot lol
