Answer: Pots of meat

Israel grumbled against Moses and Aaron: "There we sat by pots of meat and ate our fill of bread."

“And there in the desert the whole congregation of Israel grumbled against Moses and Aaron. “If only we had died by the LORD’s hand in the land of Egypt!” they said. “There we sat by pots of meat and ate our fill of bread, but you have brought us into this desert to starve this whole assembly to death!””— Exodus 16:2-3 (BSB)
