This snappy little stir-fry comes together in a flash. You get freshness from the flash-cooked pea shoots, substance from tofu and crunch from pepitas and sesame seeds. It's an easy crowd-pleaser. Slideshow: More Tofu Recipes
In a small bowl, whisk the vinegar with the honey, serrano and 3 tablespoons of the olive oil; whisk in the crème fraîche and season with salt.
In a large skillet, toast the pepitas over moderate heat, stirring, until golden, about 5 minutes. Transfer the pepitas to a small bowl. In the skillet, heat the remaining 1 tablespoon of olive oil. Add the pea shoots and stir-fry over high heat just until wilted, about 30 seconds; transfer to a plate.
Add the tofu and two-thirds each of the pepitas, sesame seeds and dressing to the skillet. Stir-fry over moderate heat until the tofu is warmed through. Season with salt and transfer to a platter. Top with the pea shoots and the remaining pepitas, sesame seeds and dressing and serve.
The dressing can be refrigerated overnight.
