Preheat oven to 350*F (175*C).
Mix crust ingredients in a large bowl. It will form a soft dough ball.
Press dough into a 8x8 non-stick pan and bake in the oven for 10 mins.
Meanwhile, in the same bowl, whisk the eggs. Add flour, honey, lemon juice and zest. Mix well. The flour may seem a bit clumpy. Don't worry, the clumps will disappear when baked.
Add the blueberries and mix.
When the crust comes out of the oven, pour the egg mixture over the crust. And put it back in the over for 20 mins, or until center is firm.
Allow it to cool before cutting into squares.
