Bring a large pot of water to a boil. Add the ramen noodles and cook according to package instructions. Once cooked, drain and set aside.
In a bowl, whisk together tahini, soy sauce, sesame oil, sriracha, ginger, and minced garlic until smooth. Add a splash of vegetable broth to thin it out if needed.
In a large pan, heat a teaspoon of oil over medium heat. Add assorted vegetables and sauté for about 5-6 minutes until they are tender but crisp.
Add the cooked ramen noodles to the pan with vegetables. Pour the tahini sauce over the noodles and gently toss everything together until well coated. If the mixture looks too thick, add more vegetable broth to achieve the desired consistency.
Remove from heat and divide the spicy tahini ramen noodles into bowls.
Top with sliced green onions, sesame seeds, and fresh cilantro for added flavor and freshness.
