It's not honeyed burgers, it's either lunch boxes or the other honey kind of item (I forgot the name), it just looks like a jar, I think. To eat the lunchboxes, just get in front of them and press E. Everytime you press E, you'll eat one, but it doesn't look like it because they spawn in the same spot. Keep pressing until the box disappears. Then, buy more lunchboxes again and repeat. If you run out of money, close the game, open the save file and change the money value, then open the game again. Someone explained it some pages back. I think there's a limit or something so just don't give yourself a million or some crazy amount, 5k was enough for me.
Edit: It's called honey milk, it's right next to the lunchboxes.
