Have you tried overnight oats? Works real well with rolled oats, so I hear.
Steel cut oats should be everywhere!! I prefer them too. Fortunately they're accessible to me, now anyway. When I do eat them Bobs Red Mill is my preferred brand. What about an online purchase? Like vitacost.com https://www.vitacost.com/bobs-red-mill-organic-steel-cut-oats-24-oz/?pd_section=pr#ProductReviews

or even amazon?
