Heat a tablespoon of oil in a non-stick pan and cook onion in it on low heat until it turns soft and deep brown in color. Remove onions to another bowl. Add remaining oil to the same pan and cook ham or sausage in it until it turns golden brown at the edges.
Add spinach to it and cook everything together until the spinach wilts. Meanwhile, whisk the eggs with milk, salt, black pepper, and Dijon until well blended.
Preheat the oven to 175 degrees C and grease a baking dish with butter. Place the ham and spinach mixture into the buttered dish.
Then, evenly spread the onion over it. Now, add half of the cheese on top of the onion mixture and pour egg mixture in it. Roughly break the croissant into pieces and place them on top of everything. Spread the remaining half of cheese on top and then cover the baking dish with a foil.
Bake it covered for 20 minutes and then uncover and bake for another 5 to 8 minutes until the top is light brown in color. Slice, serve, and enjoy!
You can also assemble the ingredients in the dish as instructed a day before and then bake everything before serving. Use fresh spinach for better results.
