Cook noodles according to package instructions. Drain but reserve the noodle water and set aside.
In a saucepan over medium heat, melt the vegan butter. Add plant milk, and seasonings (or use the seasoning packet if your instant ramen has one). Next add in Dairy-Free Shredded Cheddar and stir to melt.
Add in the noodle water, adding more for a brothier noodle experience. Stir in sriracha and then add the noodles back in. Toss them to coat in the cheesy sauce, then serve immediately.
Top with green onions, sesame seeds and whatever else you like!
