1Preheat your oven to 350°F (175°C).
Cook the instant noodles according to the package instructions, then drain and set aside.
In a large bowl, whisk together the eggs, lemon juice, and low-fat milk until well combined.
Heat the olive oil in a skillet over medium heat. Add the chopped onions and cook until they are translucent, about 5 minutes.
Add the chopped broccoli to the skillet and cook for another 3-4 minutes until slightly tender.
In a large mixing bowl, combine the cooked noodles, sautéed onions and broccoli, and the egg mixture. Mix well.
Pour the mixture into a greased casserole dish and spread it out evenly.
Sprinkle the grated cheese evenly over the top of the casserole.
Bake in the preheated oven for 25-30 minutes, or until the casserole is set and the cheese is golden brown.
Remove from the oven and let it cool for a few minutes before serving. Enjoy your Lemon Egg Noodle Casserole!
