Seth Mason's life as a macaroni and cheese food truck owner in Austin, Texas, is pretty good, except for one thing: he'd like to find a man to share that life with. As part of an organization Seth founded, he donates leftovers to the local homeless shelter, and meets Ben, a new employee. He's a preppy guy, and very much not Seth's usual type, but the attraction is strong and not going away. Ben's just moved to Austin from Connecticut to take a job as a case manager at the Austin City Mission, the first time he's left home and family. But only a short time after he starts work, he meets a man who, though he looks like an extra in a surfing movie, intrigues him. He's hardly seen what life in Austin has to offer, and yet finds he wants to discover that with Seth's help. The passion burns hot between them—hotter even than Austin in the dog days of summer, and neither man can deny it. As they grow closer, both must decide if they have the necessary ingredients for lasting love, or if the relationship will go up in smoke.

Josh and Aubrey become a couple after meeting at work. The job is on a mac-n-cheese food truck, and their boss, Seth, has offered both of them the chance of a lifetime at their age—to manage his new, second truck. As they begin to work together more, their feelings deepen. But Josh has a secret; one he feels he must tell Aubrey before their relationship gets more serious. He’s bisexual, and has ex’s of both sexes. One of those is Kristoff, Josh’s most long-standing relationship to date, who left Austin and Josh behind to answer the call of duty at his parents’ business. Now Kristoff is back and wants to reconnect with Josh. Seeing the only person he’s ever loved, just as he’s falling for Aubrey, completely throws Josh. Just when he thought he could finally forget the man and be happy with someone else; old feeling resurface. Aubrey’s confused, too, since she feels a strange pull to this man she should regard as competition for Josh’s heart. As the three navigate a possible ménage situation, they each have doubts about its viability. But in the end, will they be left with nothing, or will the three get a taste and be hooked?
