Start by heating about a tablespoon of oil in a skillet over medium heat. Add your sliced onions and a pinch of salt. Stir occasionally for about 20-25 minutes until they’re golden brown and deliciously sweet.

While your onions are caramelizing, cut the turkey into small lardon-sized pieces and cook them until crispy. Set them aside on a paper towel to drain.

In a large bowl, whisk together flour, baking powder, and salt.

In another bowl, whisk the eggs, oil, and milk until smooth. Combine the wet mixture with the dry ingredients and stir until just combined.

Gently fold in the caramelized onions and turkey lardons, then pour the mixture into a greased cake pan and smooth the top.

Pop it in a preheated oven at 350°F (175°C) and bake for about 30-35 minutes, or until a toothpick inserted into the center comes out clean.

Let the cake cool for a few minutes before slicing and serving.

If desired, sprinkle fresh herbs and a touch of cheese on top right before serving.
