What to do with oatmeal?

I really liked oatmeal just boiled in milk with (sometimes) some peanut butter. Felt like a lean, clean meal. Oatmeal releases energy slowly so it's a good way of getting carbs without getting fat.

How do I make oatmeal as a vegan? I don't have access to stuff like almond milk where I am, so instead of substituting milk if you want to suggest different recipes altogether that would be nice. I also prefer ease over taste.
