What is a hearty, cholesterol-lowering breakfast that is easy to make ahead of time?

My habits have me eating out every morning on the way to work, picking up a biscuit and hash browns. :( Delicious, but bad for cholesterol)
I've tried oatmeal and toast, but without something more substantial, with protein, I don't make it to lunch without cravings.

https://www.self.com/recipe/banana-nut-overnight-oats. The oats are good for cholesterol. Use almond milk and a few nuts to keep you full.  Chia seed and flax are also good for you and filling.

LaraBars are good.  I eat the blueberry muffin ones and there is no cholesterol in them.

1 cup oatmeal with 1/4 cup blackberries and 1 cup low-calorie coconut-almond milk.

I find oatmeal is a good breakfast and it is very filling.

I eat Special K cereal in 1% Lactaid every morning.  

I don't really know how to answer.  The biscuit might not be so bad but and it depends on how the has browns were cooked.  If they were fried, then it's not a good choice.
