This udon noodle recipe combines the thick, robust noodles with a colorful mix of roasted vegetables with a hard-to-stop-licking-the-spoon creamy (dairy-free) sauce made with tahini and toasted sesame oil.
Whisk the sauce ingredients together in a bowl until smooth. Set aside.
Noodle bowl
Preheat the oven to 425 (220C) degrees
Toss together the eggplant, shiitake, bell pepper, tomatoes, onion, olive oil, red pepper and salt on a large rimmed baking sheet. Roast 20-25 minutes, until the vegetables are tender and the eggplant is golden brown
Add the green onion and spinach to the pan and stir until the leaves wilt.
Prepare the udon noodles according to package directions. Pour half the sesame sauce over the noodles and toss with tongs until they're coated.
Portion the noodles into bowls and top with the vegetables. Drizzle the remaining sauce over and serve.
Notes
The roasted vegetables can be made 5 days ahead. Just reheat in the oven or microwave for a few minutes when you're ready to assemble the bowl.
Sesame sauce keeps well up to a week, refrigerated. If it thickens up, stir in a tablespoon or so of cold water to loosen it.
Cooked udon noodles can be chilled up to 3 days and refreshed under hot running water before serving.
