Keto Tuna Melt in Puff Pastry

This is a really good pastry - all keto!  I think you will love it.  If you love tuna melts, the combo of these two are simply sublime.  I picked up all of my special flours at an organic grocery, here in town at  Pomme in Coquitlam and I always get my Almond Flour at Costco which is good and very inexpensive!  

Oven 400 degrees

Pastry:  5 tbsp. vital wheat gluten, 1/4 almond flour, 2 tbsp. oat flour, 1 tbsp. coconut flour, 1/4 tsp. baking powder, 1/4 tsp. xanthan gum, pinch of salt, 1/2 cup chilled butter, 1/3 cup cold water plus another 1 tbsp.  

Egg Wash:  1 egg, 1/2 tbsp. water, whisk together.

Tuna Melt:  1 can water packed tuna, drained, 3 tbsp. mayonnaise, 1/2 celery chopped, 2 tbsp. red onion, 1 tsp. dried parsley, pinch of pepper, 1 tsp. lemon juice, 1/4 cup cheddar shredded.

Mix dried ingredients and then cut the cold butter into the flour.  Add the water and then mix or knead the dough.  The dough will be almost creamy. Maybe if you mix by hand it won't be.  I put mine in the food processor.  Dust your hands with more vital wheat gluten and shape dough into a ball and put into a Tupperware or Saran Wrap and refrigerate for at least 30 minutes.

In the meantime, mix up tuna mixture and set the oven to 400 degrees.

When you take the dough out of refrigerator, dust the counter again and roll out into a rectangle with a rolling pin.  You can either make individual pies or as I did, one big one like a roll.  

Once you roll it out, lift with a large spatula and put onto a very lightly Pam sprayed baking pan.  Layer tuna melt mixture on 1/2 side of dough.  Roll up the other side over tuna melt mixture and seal roll.  I did find the dough warms up quickly so can fall apart a little, just have confidence and work your roll like you are sculpting a masterpiece!  When you are done, brush egg wash over dough and decorate with dried herbs or fresh dill like I did!

Pop into the oven and bake for about 20-25 minutes.
