Prepare the ingredients like this.

First, I will make tomato sauce. The skin of a tomato is tough, so you use it after blanching it and peeling it. Slightly cut the bottom of the tomato with a cross.

Put the tomatoes in boiling water and when the cuts are slightly open, remove them and put them in cold water immediately to peel them well.

I'll prepare the ingredients for the sauce! Chop the garlic and onion into thickly.

Pour olive oil into a skillet and stir-fry garlic and onion until brown.

Mash the peeled tomatoes well with your hands.

Put the crushed tomatoes in a pot and stir well.

Add 1/2 cup chicken broth

1 tablespoon of tomato ketchup

Add 1 bay leaf and a pinch of pepper and simmer until it boils in half.

Cut off the tip of the bell pepper with a knife and then remove the tip by hand.

Cut the bell peppers into the size of your fingernails.

Cut mushrooms, zucchinis, and chicken breasts into small pieces.

Slice the garlic.

We will use chili oil to make spicy quesadilla.

After pouring chili oil on the pan, stir-fry the garlic first.

Put the chicken breast in here and sprinkle a bit of pepper.

When the chicken breast is cooked, stir-fry the other vegetables together, then add 1 tablespoon of red pepper paste and mix well.

Then, add the tomato sauce and stir-fry until the water evaporates.

It's good to use a grill pan! Place tortillas on a grill pan and sprinkle pizza cheese.

Put the stir-fried ingredients on top, add cheese again, and cover with tortilla.

Turn it over until the cheese melts and make a grill mark!
