Linoleum floors, steel tables and a stainless steel stove would make anyone feel like a high-end chef. But thereâs nothing fancy about Mullensâ work. Itâs all about the vegan cheese sauce he personally makes to fuel a growing business that is now nationwide. With the help of PayPal, the payment-exchange service, Mullens has seed money he believes is giving his company a solid foundation. Mullens, 25, graduated recently from N.C. A&T with a degree in industrial engineering. But his first love is the sauce he has spent the past couple of years perfecting. Itâs a vegan sauce, which means it includes no animal products like dairy and is made purely from plants and seasonings â primarily potatoes and carrots turned into a golden sauce that sticks to pasta like a creamy cheese barely distinguishable from the real thing.
