Preheat oven to 450 F. Once preheated, bake calamari for allotted time on box (usually 10 min).
Meanwhile, in a deep and large pan or wok, heat olive oil on med-high. Add mushrooms, cooking for 5 min stirring occasionally. Add green beans and cook another 3-4 min.
Meanwhile, whisk soy sauce, garlic, brown sugar, broth, sriracha and sesame oil together in separate bowl.
Add coleslaw, red pepper and sauce to wok, then noodles, stirring to mix together. Cook for 3-4 min until noodles are well coated with sauce and veggies are tender. Remove from heat and stir in green onions.
Garnish noodles with sesame seeds and slices of red chili pepper, then top with cooked calamari.
Serve immediately and refrigerate leftovers up to five days.
