Cook the rice noodles in a well-salted pot of boiling water until al dente. Drain and toss with a small amount of oil to keep the noodles from sticking together.
In a small saucepot, whisk together the sriracha, honey, rice vinegar, soy sauce, lime juice, and vegetable broth. Taste for seasonings and adjust as needed. For more spice, add 1 tablespoon sriracha at a time. For more sweetness, add 1-2 teaspoons honey at a time.
Bring to a simmer over medium-high heat. In a small container, whisk together 1 teaspoon corn starch and 1 teaspoon water to form a cornstarch slurry. Add this to the sauce and reduce heat to a gentle simmer over low heat.
Simmer, whisking occasionally, until thickened. This will take just 2-3 minutes. For a thicker sauce, repeat the corn starch slurry. For a thinner sauce, add an extra splash of vegetable broth.
Toss the noodles with the sauce. Serve with steamed broccoli and air fryer tofu for a complete meal.
For the complete meal
Steam broccoli until vivid green and tender. I use a steamer basket over 1 inch of simmering water, but a fine mesh sieve with a lid fitted on top also works. Season with salt and pepper, to taste.
Press the tofu for 5 minutes with a tofu press or by wrapping it in paper towels and weighing it down with something heavy, like a cast iron skillet.
Tear the tofu into bite-sized pieces. In a mixing bowl, whisk together 1 teaspoon oil, 1 tablespoon nutritional yeast, ½ teaspoon black pepper, and ¼ teaspoon salt (can adjust to taste as needed.) Toss the tofu in the seasonings and add more oil as needed to fully coat the tofu.
Transfer the tofu to the air fryer rack. Air fry at 375F for 15-20 minutes, or until crisp and golden. Serve the broccoli and tofu with the noodles.
Notes
This is a light sauce. For super saucy noodles, I recommend doubling the sauce recipe.
Sriracha: I know there has been a shortage of sriracha over the past couple of years. I used a store-brand version and it's not as good as Huy Fong but it does the trick. This recipe should also work with harissa, garlic chili sauce, and sambal oelek. Just make sure to start with a small amount and add slowly, as spiciness varies widely from brand to brand.
The sriracha sauce is spicy but not overwhelmingly spicy. If you're not a big fan of spicy food this may not be a great recipe for you. The sriracha can be decreased to 2 tablespoons, and the other ingredients can be increased to contrast the spice. Feel free to experiment with the sauce!
The tofu and broccoli are optional but this is how I usually make the meal. If you don't have an air fryer, I recommend this marinated baked tofu or you can just add edamame.
