Potato Tomato

From BoardGameGeek:

Baked potato. Baked tomato. Which one is the most popular side dish? No one knows how it started. Rumour has it, the rivalry began when one of the potatoes claimed that baked potato is the most popular side dish. A fiery tomato challenged the claim, asserting that the most popular side dish is, in fact, baked tomato! The argument quickly spread around the world of side dishes. Hence began the “PotatoTomato” conflict! However, the Alliance of Fruits and Vegetables has yet to get involved in this nonsense... for now! Both the Potatoes and the Tomatoes have started sending spies to sabotage each other. You are one of the spies. Your mission is to reveal other players' roles. When all role cards of a single player are exposed, that player - and everyone on the same team - is eliminated. Be careful - Teams can be changed at any time during the game. Trust no-one!
