This vibrant mustard-crusted tofu with kale and sweet potato is a fantastic choice for a nutritious vegan dinner. The sharp, savoury punch of whole grain mustard provides a beautiful crust for the tofu, which contrasts perfectly with the earthy sweetness of the vegetables. Zesty lime juice adds a bright finish, lifting the ginger and onion aromatics for a well-balanced plate that feels both light and satisfying.
Ideal for a midweek meal, this dish is packed with plant-based protein and iron-rich greens. Using a lidded pan to steam the sweet potatoes ensures they become perfectly tender while keeping the prep time to a minimum. Serve this colourful stir-fry as a standalone main or alongside a portion of brown rice for a more substantial evening meal.

Ingredients for Mustard-Crusted Tofu with Kale and Sweet Potato
1 400g package firm tofu
120ml whole grain Dijon mustard
4 tablespoons vegetable oil, divided
1/2 medium onion, sliced
1 tablespoon minced peeled fresh ginger
1 bunch kale, stem cut from each leaf, leaves thinly sliced crosswise (about 1925ml )
1 small red-skinned sweet potato (yam
about 230g ), peeled, halved lengthwise, thinly sliced crosswise
2 tablespoons fresh lime juice
How to make Mustard-Crusted Tofu with Kale and Sweet Potato
Cut tofu into eight 1/2-inch-thick slices. Arrange on paper towels; drain 10 minutes. Spread both sides of each slice with mustard.
Heat 2 tablespoons oil in large nonstick skillet over medium-high heat. Add onion and ginger; sauté 1 minute. Add kale, sweet potato, and lime juice. Cover, reduce heat to low, and cook until potato is tender and kale is wilted, about 12 minutes.
Meanwhile, heat remaining 2 tablespoons oil in another large nonstick skillet over medium heat. Add tofu; cover and cook until heated through and crisp, about 2 minutes per side (some mustard seeds may fall off tofu).
Arrange kale and sweet potato mixture on plate. Overlap tofu slices atop vegetables and serve.
