Barry Farms (online) has dried tomato powder,dices and julienned in small quantities, also peppers and much other dried stuff. I make the tomato sauce with the powder, dices and green peppers and then add a pouch of off the shelf spaghetti sauce mix. Gets very thick & tasty.

Also alfredo, dried milk (or dried sour cream) with minced garlic, salt & pepper, perhaps an off the shelf dried alfredo mix, and add a roux, simmer and serve over pasta. Add Italian sausage or andouille.
