Grease a 9x13 baking dish.
Place 12 dinner rolls in rows in baking dish and cover with plastic wrap or a towel to thaw and rise. This process will take about 3-4 hours depending on how warm your kitchen is.
Once the rolls have doubled in size preheat the oven to 350 ℉. Melt the butter and drizzle over the top. Use your fingers to press the dough down to make those signature focaccia dimples.
Zest the lemon right over the top of the dough making sure to get a bit of lemon all over the top.
Scatter the blueberries over top and again use your fingers to press them into the dough.
Bake in a preheated oven for 25 minutes or until baked through and golden brown on top.
While focaccia is baking whish together powdered sugar and lemon juice.
Once the focaccia bread comes out of the oven, let cool for 5 minutes then drizzle with glaze. Slice and serve.
