Well, it's not that odd considering the Interstellar star's mom, Jerri Hastey, is a vegan chef.
The daytime talk show host quipped back, “So she can just drive around her restaurant anywhere she wants to go.”
Chastain shared a photo of Hastey peeking out of the truck’s service window with a glass of wine in her hand, to which Chastain quickly clarified the mobile vegan kitchen does not actually serve wine.
“The funny thing is, that [photo] was on her Facebook page and she was so excited about the food truck, and I went and looked on her Facebook page and was like, ‘mom, you don’t understand the idea of a truck and wine. You cannot be sitting in the driver’s seat with a glass of wine hanging out the window!” laughed Chastain.
Chastain said the menu on the Santa Rosa, California-based food truck will feature some of the actress' favorite items, including a sloppy seed burger, sweet potato corn tacos, pancakes and strawberry shortcake.
“The last time I was here I talked about her chia pudding and that will be on the truck,” reassured Chastain.
