Cook the pasta according to package instruction, drain and set aside.
If you don’t have garlic infused oil, heat the olive oil with the garlic clove in a big skillet over medium–high heat. Remove the garlic clove, add the spinach and sauté for 5 minutes or until spinach has wilted. (It is very important to remove the garlic clove before adding the ingredients, otherwhise the food will be contamined with fodmaps from the garlic)
Add in the cooked pasta and ricotta and quickly give everything a big stir (to avoid overcooking the pasta). Season generously with salt and pepper. Toss well and serve with walnuts on top and red pepper flakes.
