smokes, thanks for the info re Quorn. They don't sell Cauldron in the U.S., unfortunately. Beyond Meat makes good chicken and burger alternatives, using mostly pea protein, I believe.
Aidell's is a question of taste, but I stay away from the ones that contain cheese because it's sort of like a deep fried Mars bar to me, overkill in the fat dept.
I like artichoke and garlic the best. The chicken/apple isn't bad although a little sweet. Spicy Mango is hot and a little sweet, the Chorizo (chicken) is good, Habanero & Green Chile is good, and if you eat pork, the Cajun style Andouille. I like the spinach feta sometimes.
Grocery Outlet often has packs on sale for 3.99, so I'll stock up when I see those as they freeze well and thaw quickly in a bowl of warm water (still in package). Safeway or Target will have sales where they're around 5 bucks. I think there are these stores near you. We've had Safeway's groovy brand Open Nature and they aren't too bad and they occasionally have sales on those for around the same price.
