In a medium pot, melt the butter over medium heat. Add the oats and cook for 30 seconds to toast.
Add the water and milk to the pot and bring it to a simmer.
Turn the heat to low and allow to simmer for 8 to 10 minutes until the oats reach a thick consistency adding more water in if necessary.
Stir in the salt, garlic powder, and oregano. Keep on very low heat.
Meanwhile, place the eggs in a medium saucepan and cover with at least 2 inches of cold water. Stir in ½ tablespoon of salt and place over high heat until it reaches a boil.
Remove the saucepan from heat, cover it with a tight-fitting lid and let it sit for 6 minutes.
Drain the water from the saucepan and transfer the eggs to an ice bath. Allow them to cool for 5 minutes before peeling.
Divide the oatmeal between 4 bowls, and top each with a halved soft-boiled egg, feta cheese, olives, and sliced veggies.
Notes
You can prepare the eggs any way you like; fried, over easy, or hard-boiled.
