Finely mince 1 clove of garlic, finely dice ½ of an onion and finely dice 7 button mushrooms
Heat a non-stick frying pan with a medium heat and add ¼ cup extra virgin Spanish olive oil
Once the oil gets hot, season it with sea salt and add the minced garlic to the pan
After about 20 seconds add the diced onions to the pan and mix
After cooking your onions for about 4 minutes add the diced mushrooms to the pan and mix
About 3 minutes after adding the diced mushrooms, add a generous pinch of freshly chopped parsley and sea salt and mix
Grab a ¼ cup of all-purpose flour and start adding it to the pan, little by little, while continuing to stir the mixture
Now grab 1 cup of milk and start adding it to the pan, just like the flour, a little at a time while continuing to stir the mixture
Once your mixture becomes into a paste, turn your burner off and transfer the mixture to a bowl and cover with seran wrap
Grab a small bowl and beat 1 egg
Grab ½ cup of bread crumbs and add to a seperate bowl
Once your mushroom mixture reaches room temperature remove the seran wrap
Using a spoon, grab some of the mixture and begin to shape your croquettes, in the size and shape of an egg
Dip the croquettes one by one into the egg bowl and coat well and then into the bowl with the breadcrums and coat well and transfer to a plate
Grab a small non-stick frying pan, heat with a medium heat and add ½ cup extra virgin Spanish olive oil to the pan
Once the oil gets very hot, start adding the croquettes to the pan without overcrowding, cook in batches
After about 1 minute turn the croquettes to cook the uncooked side and cook for another minute, then remove from the pan and transfer to a plate with a paper towel
Once all your croquettes are cooked transfer to a new plate
Garnish with fresh parsley
