Who knew Mark Cuban is a vegetarian?

He went on “Shark Tank” Sunday and became passionate about vegan corned beef, according to CNBC. He loved the low-fat, 100-calorie plant-based deli meat. Cuban and Jenny Goldfarb bonded over her “Unreal Deli Corned Beef sandwich.” Also both have grandfathers who emigrated from Romania. Here’s what Cuban said: “I’ll simplify everything. I love it. I went vegetarian. I’ll make you an offer. I’ll give you $250,000 for 20%. I’ll be on the front page of it. I’ll be the poster-child for it. We’ll hustle. I don’t mess around.”
