In a skillet, bring marinara sauce, sriracha, and water to a simmer. Add ramen noodles; cook until noodles start to soften, about two minutes. Flip noodles; continue to cook until the block of ramen loosens, another two minutes. (Don’t worry if they are not cooked through; they will continue to cook along with the eggs.)

With a spoon, make a well in the sauce. Crack an egg into a small bowl; gently slide it into the well. Repeat, one by one, making wells and sliding in remaining eggs. Cover the skillet; cook until egg whites are set, four to five minutes. Garnish with scallions and sesame seeds. Serve immediately.
