The gross reason Prego spaghetti sauce is trending on Twitter

Prego — it’s still in there.

An enterprising home cook has devised a questionable way to make a large batch of spaghetti in a flash — by mixing it all together on her kitchen counter with old-school tomato sauce. As of Tuesday morning, the classic Prego brand — launched globally by the Campbell’s Soup Company with the “It’s in there” slogan back in 1981 — is officially a Twitter trend. First shared on Facebook in April, the unorthodox cooking tutorial was reposted Monday to Twitter, where it garnered 3.7 million views in less than 24 hours.
