It's too often relegated to the crudité platter, let celery shine as the star vegetable in this easy plant-based stir-fry. Tofu provides the protein, while ginger, scallions, chili-garlic sauce, and cilantro kick up the flavor.
Stir together tamari, sesame oil, chili-garlic sauce, and 1 tablespoon water. In a large nonstick skillet, heat vegetable oil over high until just smoking. Add tofu and cook, turning once, until golden, 4 minutes total. Transfer to a plate.
Add celery (and additional oil, if needed) to skillet and cook, stirring often, until crisp-tender, 1 to 2 minutes. Stir in ginger, scallion, and cilantro; cook 30 seconds. Return tofu and add tamari mixture to skillet. Toss to coat; serve.
