Preheat oven to 400F degrees.
Prepare orzo according to the directions on the box - making sure to save at least one cup of pasta water when straining.
Next, add garlic, feta, olive oil, salt and red pepper flakes to a baking dish.
Bake for 30 minutes.
Remove from heat and lightly mash up the garlic and then stir the feta into it.
Add the spinach and pasta and lemon juice and stir.
If it's dry , add a little pasta water (stirring 2-3 tbsp at a time) to make the sauce creamier.
Plate and top with a drizzle of white balsamic glaze and fresh cracked pepper.
