"After getting out of the NFL, [Eric] went to this healer and is very healthy," Simpson, 30, told Jimmy Fallon of her vegan husband-to-be. "For Thanksgiving we have to make a Tofurkey! It doesn't sound right! It's gonna be jiggly and weird."
And while the singer, who just released her Christmas album, acknowledges that "when [Eric] cooks vegan, it's good," she also admits that she comes from a very different background.
"I'm from Texas – I'd fry a steak," she laughed. "We eat all casseroles and giblets!"
Dietary preferences aside, Simpson said she's "very, very happy" in her relationship, and that Johnson proposed to her in the spot they met: her home.
"It was romantic," she said of the Nov. 11 proposal. "He kept the ring hidden in a shoe somewhere in my house ... [and] had talked to my dad, he had talked to my mom, he even talked to my sister. Everyone knew but me!"
