A very healthy breakfast option. But steel cut oats can be a pain to cook and take a bit of time. My suggestions are to make more than one serving, and use the overnight cooking method.
In a sauce pot, place 4 cups of water. Bring to a boil. When water is boiling, stir in 1 cup of oats and 1/4 tsp of salt. Cook for one minute (no more, no less). Stir as needed if bubbling up. At the end of the minute, stir one last time, turn off heat, place a lid on the pot. Now let the oats sit overnight. They are ready to eat in the morning and can be refrigerated for easy reheating.
Top with whatever you like. I use dried blueberries and a small amount of dark brown sugar as a standard. Some people add in non-dairy milk, butter. Nuts. Granola. And all kinds of fruit. Peanut butter.
Tip from my friend Joe. Put 1 part oats in a rice cooker with 3 parts water. Do this the night before. If your cooker is programmable, set it. Otherwise turn it on in the morning and 20-30 minutes later, you have perfect cooked oats with a lot less work.
