Hm.

For snacking or small "meal" quantities, how about mixing up your own "trail mix" with select ingredients? Jerky that you chop into smaller bits, carob nibs or chocolate chips, (dried) cranberries/cherries/blueberries/raisins, sunflower seeds, a "granola" type cereal product that doesn't contain wheat/oats, honey or molasses (as a sweetener and to help hold it together). Can form into bars, or without the honey/molasses can "bag it" for portable refueling. Can add tapioca flour to aid in binding, and to add a zap of carbs (it's all carbs). Can add pea protein powder if you feel you need a bit more protein in the mix. Can mix into a non-dairy "yogurt" (ie, Silk's product, which is based on soy. Can bake into sheets, then cut up for wrapping as to-go snacks. High-calorie, lots of proteins/fats, and a good amount of carbs. And you control the ingredients, so you can avoid the stuff you don't want.

Off-hand, I can't think of any "bar" that doesn't contain dairy, nuts, oats or coconut. All of the ones I know of contain one or more of those ingredients from your "no" list, even their "no dairy/nuts" versions and their "vegan" versions.

If at home, you could make up a blend. Something like ... leafy greens, avocado, tofu, sunflower/chia/hemp seeds, carob/chocolate chips, a soy- or pea-based protein powder (instead of whey or yogurt), fruits. Adjust ingredients to be the mix of macro-nutrients you're looking for. Sufficiently "loaded" with a variety of ingredients, you could make it a meal replacement. Would need cooling, so it's not all that suitable for taking it with you (on a ride, for a mid-ride snack).

EDIT: Ach. Just realized that "cacao" is on your "verboten" list.
