Preparation

For the vegetable stock: Step 1

In a 4-quart pot, heat the oil over medium-low heat.

For the Harissa: Step 1

Roast the bell pepper directly over a medium gas flame until charred all over, about 2-3 minutes per side. Set aside to cool.

Step 3

Add the onion and cook until golden, stirring occasionally, about 5 minutes.
