Heat olive oil in the pan. Saute mushroom slices on high heat for 5 minutes.
They will become brown. Add oregano to it and mix well.
Arrange all the ingredients required for making pizza (basil pesto, feta cheese and veggie toppings)
Take a big whole wheat pizza base and apply olive oil and butter on it.
Apply basil pesto on it.
Top the prepared base with sliced cherry tomatoes, spinach (keep aside some spinach for garnishing ), mushrooms and feta.
Sprinkle black pepper powder on it.
Bake in the preheated oven at 220 C for 15 minutes. Remove and arrange fresh spinach leaves on it.
Cut it into wedges and serve.
Notes
Note:If you do not have Feta cheese, you can use the fresh cottage cheese. Just mash it with salt and a little lemon. It will give a similar taste like feta cheese.
