Primary discovery after a month on paleo

Grain is poor-people food.  

It's very low-taste, significant calorie, and low nutrition.  What people eat if they can't afford anything else.  A month in, and while I'm not perfect, I can easily see a future now, where bread, rice & pasta are entirely gone from the diet. 

Eating sandwiches now sucks.  I'd rather the meat and the cheese and the pickle or sauerkraut. Indeed, I've been eating them that way. 
The bread minimizes all the good strong tastes from the meat, cheese and pickle, adds useless calories, and requires all these condiments to make the sandwich tasty again, after you've damped the lovely flavors of the real ingredients.

Pasta, Pancakes, and Rice, and bread are all simply methods for me to get tasty grain-coverings into my system, while having some bulk.  Maple syrup, meat sauce and meatballs, Paneer Makhani, peanut butter and honey.  Whatever.  Grain is a delivery mechanism that is both unnecessary and flavor-damaging.  Bad news.  Peanut butter and jam is better in celery anyhow.  Paneer makhani does just fine doubling or trebling the amount of paneer.  More meatballs with some chunky mushrooms, onions, and red peppers makes the pasta unnecessary, and indeed a detriment to a high-flavor meal.  I haven't solved the syrup delivery problem without bread yet.  You simply don't get enough maple-y goodness from dunking your bacon and sausage in the syrup.

Of course, you can deliver some awfully good sugars in your grains (Napoleons, layer-cakes, homemade chocolate chip cookies.), but that's about all you need for all the value you can get from grain.
