It took me until my last seventeen hours wired, but I finally got some grains into my diet. I poured some pasta sauce into my blender and then added a bit of whole wheat pasta. I don’t remember the exact amounts, but I think that it probably about a cup of cooked pasta (rigatoni) and perhaps a little bit less sauce by volume. I turned on the blender for several minutes before adding a little bit of water to thin it out. I tested to see that it would pass through a straw and into my mouth before adding a little bit of nutritional yeast and blending for a few more seconds.
The taste isn’t great. The tomato flavor is very much stronger than I would like because it’s more sauce than I’d usually use for this amount of pasta, but I’m glad to have solved the problem of how to imbibe some whole grains, even if the practical significance is minimal at this point.
