Whisk the eggs, milk and salt together in a bowl and set aside.
Preheat the oven to 400 F.
Saute the onions in a cast iron skillet on medium high heat till they are translucent.
Add the frozen vegetables to the skillet and cook for about 2-3 minutes.
Mix in all the dry spices together and continue cooking for another 2 minutes till the flavors come together.
Finally pour the egg mixture into the pan and make sure the egg mixture settles in evenly. Cook for a minute or till the eggs at the edge of the pan begin to set.
Put the skillet in the oven and bake for 8-10 minutes or until the eggs are set.
If you desire a crispy top then broil the eggs for a minute.
Once the eggs are done rest them for 5 minutes and then serve.
