Method
Step 1
Pita bread croutons: Place a pan on medium-high heat with a generous knob of butter and a drizzle of olive oil. When the butter has melted, add the croutons and toss to coat. Toast them in a single layer for 3-4 minutes, moving them around with a spoon, until golden and toasted. In the last 30 seconds, season with salt. (If your pan is too small, toast the croutons in batches).
Step 2
Soup: heat up the soup by adding it to a pot over a medium heat. Bring the soup to a simmer. This should take about 5-8 minutes. When heated through, season to taste.
Step 3
Serve: Serve the soup dished up in a bowl topped with parsley and buttery croutons on the side.
