Since it has gotten colder, I am not having salads every day like I was in the hot summer weather, and I still want to have the main “filling” part of my OMAD meal to be some kind of healthy vegetarian food. What I have been doing, is sautéing fresh thinly-sliced cabbage in coconut oil, and then I add an egg or two on top just before it is done, put the lid on and steam it until the egg is cooked but still soft in the yolk.
I add a little butter to this, and lemon pepper, and it makes a really delicious, low carb, meat-free vegetarian meal, and since you can have as much cabbage as you want, it always fills me up really well.
Sometimes, I also add a few leaves of kale or spinach along with the cabbage, or even carrots and onions. Any which way that you make it, it is a healthy meal and very filling.
On days when I do not want anything heavy to eat, I will have a large sliced apple and cheese cubes, along with a hot cup of coffee, and this is also a filling meal for me.
