Keeping Kids Paleo- PB&J

I know a lot of the people who use my recipes are in the same, or similar, boat that I am. You have children who did not start out Paleo.  Though we are on the right track to keeping them as healthy as possible, they experienced the Standard American Diet, or at least a version of it, prior to Paleo life.  In general, my kids don't ask for pre-paleo foods, except for 2 big exceptions.
1)PB&J- No matter what is available, if you say the word 'Lunch' Loralei will ask for a PB&J. She loves them! I often refer to lunch as 'snack' just to avoid having to hear her ask for it.
2) Grilled Cheese- I could sneak in veggies, meats, etc into Loralei through a grilled cheese. As long as there was butter slathered bread and cheese, she would generally eat and LOVE it. She will occasionally ask for one. 
And I give it to her....
No, not the gluten, grain filled bread versions, but a version with this bread.  I am not the inventor of this recipe, and I've seen several variations going around the Atkins/low-carb type recipe circles for years and years. I can vaguely remember, probably 15 years ago, when my dad was doing a stint on Atkins, this style of recipe circling. 
I was reminded of this recipe recently from She Cooks He Cleans website (which I love by the way).
Here is the basic recipe I do for the kids. Add herbs, spices, change up the fat, and you can get tons of different breads.

Micro-Bread
1/4 C Almond Flour
2 Tbsp Ground Flax (I course grind it in a coffee grinder)
1 tsp baking powder
1/2 tbsp butter
1 egg

In a ramekin, melt butter. Allow butter to cool slightly. While it is cooling, mix remaining ingredients, except egg, in a small bowl.  Mix egg into butter, and add mixture into dry ingredients. Mix well and return batter to ramekin.

 Place in microwave and turn on high for 1 minute.  Remove (carefully, it will be hot) and make into your favorite sandwich (within Paleo parameters of course).
