This one is a real pickle — it's extremely simple, and doesn't look spectacular, but packs a serious punch of flavor and deliciousness. You can easily upgrade or downgrade the recipe based on your liking, use different ingredients, but as long as you make ground meat under a blanket of mashed potatoes, it's gonna be fine ;-)
There is literally no easier recipe in the world, that tastes so good and takes only few minutes to cook, including rice cooking time! I always do it during hot summer days, because it's a no-brainer.
You can serve it as a main dish with more fancy toppings, or as a side dish, but also it's a great addition to bento or a small snack!
