I would like to make the type of shells that are stuffed with cheese
(usually ricotta with some Romano or Parmesan). I was buying some
frozen shells at Safeway that I really liked, but apparently they have
been discontinued. I really liked them as I could make up a batch of
spaghetti sauce and freeze in portions. Then pull out some sauce and a
few shells for a quick and easy meal.

I have not been able to find any large shells to buy, either dry or
cooked (like Boutoni or something). And I don't like stuffed
ravioli.

Any suggestions for where I can find these pasta shells? I am open to
dry pasta, cooked pasta, and even stuff shells if it just cheese and
light seasoning. No sauce, meat, or veggies.
