Rebecca Arnold wants to make one thing clear about her new fast-food restaurant, Whole Heart Provisions. Yes, it’s nutritious—heck, it’s even vegan. But there are limits to all that clean living.

“It’s healthy, but I’m not saying it’s the healthiest food in the world. I mean, we do have a fryer,” the chef/co-owner says of the Allston spot slated to open later this month. “The menu’s much healthier than other things you would get on the run. It’s basically things that I would want to eat but I can’t find when I’m on the run in the city. It’s flavorful.”

Drawing on her experience at Sarma and Alden & Harlow, Arnold has devised a menu centered on five styles of bowls, each served over the guest’s choice of greens or grains. A Vietnamese-inspired style features spicy peanut sauce, a sugar-and-spice peanut crumble, smashed cucumber, raw carrots and zucchini, while the Seeta option includes coconut curry sauce, crispy lentils, a shaved carrot and zucchini salad, marinated tomatoes with ginger, smashed lemony chickpeas and curried cauliflower.

Such bold flavor combinations lured co-owner James DiSabatino, who runs the Roxy’s Grilled Cheese empire, to team up with Arnold, who once staged at Roxy’s. When the space next door to the Roxy’s brick-and-mortar became available, he reached out to see if she’d be interested in partnering with him.

“I’m a fan of Rebecca’s cooking,” he says. “I think she brings a completely unique point of view to it. If 15 vegan restaurants open in Boston next year, I still don’t think they’ll be close to what she’s doing.”

The layout of the space is similar to that of Root, which previously occupied the address and closed in July. There’s seating for 19 on the edges of the restaurant and a huge menu board on one side of the counter. Drinks are expected to include matcha lemonade, horchata iced coffee and on-tap kombucha.

“Allston’s a really unique neighborhood. It’s diverse enough that people have alternative lifestyles and eating habits,” DiSabatino says. “The idea is to take this somewhat alternative concept and make it approachable to everyone.”
