Heat a very large skillet or saute pan over medium-high heat.
In a small bowl, crack the eggs and use a fork to whisk them together well (you can use as many eggs as you like, we like a lot of scrambled eggs in our fried rice so I normally use 6).
When the pan is hot, add 1/2 tablespoon of oil (reserving the remaining 2.5 tablespoons) and swirl the pan to spread the oil across the bottom of the pan.
Add your eggs and cook, stirring often, to scramble and cook the eggs. When the eggs are cooked through remove them from the pan and place them in a small bowl, set aside.
Return the pan to the heat and add the remaining 2.5 tablespoons of oil.
Add the cooked rice and saute in the oil, breaking up the rice. If it starts to stick the to bottom lower the heat and feel free to add some additional oil.
Add the cooked ham and mixed peas and carrots, stir to combine, and cook for a minute or two until the vegetables warm through.
Add the soy sauce, onion powder, and garlic powder. Stir to combine well.
Add salt and pepper to taste and feel free to adjust the soy sauce, onion powder, and garlic powder to your liking.
Stir in the scrambled eggs.
Remove from the heat and serve hot.
Notes
It'll take roughly 2 cups of uncooked rice to make 5 cups of cooked rice.
I prefer using leftover rice but I have made fried rice with fresh cooked rice many times, too. The texture is just a bit different. The leftover rice doesn't clump together as much as the freshly cooked rice; they taste the same, though. Leftover rice will produce an end result most like take-out fried rice.
You can use any kind of ham you have; we also like cooked shrimp or diced cooked chicken in this recipe. It's very flexible.
The amounts/ratios of each ingredient can be adjusted to personal taste; just adjust the soy sauce, garlic powder, onion powder, and salt to taste.
