Chilled Soba with Tofu and Sugar Snap Peas

This chilled soba with tofu and sugar snap peas is a beautifully light and refreshing vegan dish, perfect for warm days or a nutritious lunch. The recipe features nutty buckwheat noodles tossed with crisp snap peas and wilted spinach, all brought together by a complex, savoury dressing infused with shiitake and kombu. The addition of silken tofu provides a delicate texture that balances the crunch of the fresh vegetables and the zingy heat of the ginger matchsticks.

Inspired by traditional Japanese flavours, this plant-based meal is as healthy as it is satisfying. It is naturally high in fibre and provides a clean, energy-boosting alternative to heavier pasta dishes. Serve it in shallow bowls for a sophisticated mid-week dinner, or prepare the components in advance for a quick, chilled assembly. The citrusy ponzu and toasted sesame oil ensure every bite is packed with bright, umami notes.

How to make Chilled Soba with Tofu and Sugar Snap Peas

Simmer mushroom in water in a small saucepan, covered, 15 minutes. Add kombu and barely simmer, covered, 5 minutes. Remove from heat and let stand, covered, 5 minutes. Strain through a fine-mesh sieve into a large glass measure, pressing on and discarding solids. Return 475ml liquid (add water if necessary) to saucepan. Add soy sauce, mirin, ponzu, sugar, and 1/4 teaspoons salt and bring to a boil, stirring until sugar has dissolved. Remove from heat. Stir in sesame oil, then cool in pan in a large ice bath.

Blanch sugar snaps in a large pot of unsalted boiling water until crisp-tender, about 2 minutes. Transfer with a slotted spoon to a large colander set in ice bath to stop cooking. Lift colander to drain. Transfer sugar snaps to a bowl. Meanwhile, return water to a boil. Blanch spinach until just wilted, about 30 seconds, then cool and drain in same manner. Squeeze out excess water. Add to sugar snaps.

Return water to a boil.

Add noodles and cook according to package directions, stirring occasionally, until tender. Drain in colander and rinse with cold water. Cool in ice bath until very cold (add more ice to water as necessary). Drain well.

Carefully drain tofu and pat dry. Cut into 3/4-inch cubes.

Whisk sauce, then pour 350ml sauce into a large bowl. Add noodles, sugar snaps, spinach, and half of spring onions and toss. Serve in shallow bowls, topped with tofu, remaining spring onions, and ginger. Drizzle with some of remaining sauce and serve remainder on the side.
