Loma LindaPlant Based Meats (Swiss Stake with Gravy, (13 oz.), 3 Pack)

What is the best way to store these after opening?

Can you grill these? If 30 come in a can how can I keep them fresh if I am only eating a few at a time?

are these the same texture and taste as their veja-links?

Why did the price on these increase so significantly in the past few months?
