A 200g pack of steel cut oats contains minimally processed whole oat groats, chopped into small pieces, offering a nutty flavor, chewy texture, and sustained energy due to high fiber, protein, vitamins (like B vitamins), and minerals, making it a healthy, less-processed breakfast option that takes longer to cook than rolled oats but keeps you full longer. 
What Steel Cut Oats Are:
Whole Grains: They are whole oat groats (kernels) that have been chopped into two or three pieces by a steel blade, hence the name.
Minimally Processed: This is one of the least processed forms of oats, retaining the bran, germ, and endosperm.
Texture & Flavor: They offer a distinct, chewy texture and a nutty taste, unlike the softer rolled oats.
Cooking Time: Because they aren’t steamed and flattened, they take longer (around 20-30 minutes) to cook than instant or rolled oats.
