Start by cooking the ramen noodles: Place them in a pot of boiling water, and cook according to the package instructions, but remove them from the heat about one minute earlier than the suggested time to keep them from becoming mushy. Drain the noodles and set aside.
Meanwhile, heat the sesame oil in a large skillet or wok over medium-high heat until shimmering.
Add the sliced onion to the skillet and sauté for 1 minute. Then, introduce the minced garlic and grated ginger. Stir-fry for an additional 2 minutes, or until the mixture is aromatic and the onions are soft.
Next, add the sliced red and yellow bell peppers, broccoli florets, and snap peas to the skillet. Stir-fry the vegetables for about 5-6 minutes, allowing them to cook until they are just tender yet still crisp.
In a small bowl, combine the Sriracha sauce, soy sauce, rice vinegar, and honey/agave syrup. Mix thoroughly to create a flavorful stir-fry sauce.
Add the cooked ramen noodles into the skillet with the sautéed vegetables. Pour the prepared sauce over the noodles and veggies. Gently toss everything together for 2-3 minutes until the noodles and vegetables are well coated and evenly heated through.
Once everything is well combined and heated, remove the skillet from heat. Garnish your dish with chopped green onions and a light sprinkle of sesame seeds for a lovely finish.
