Heat a drizzle of olive oil over medium heat, then add in the sliced sausages. Sauté until nicely browned, then remove from the pan and set aside.
In the same pan, add the chopped onion and let it soften. Next add in the chopped bell peppers and zucchini, along with your seasonings. Sauté for 2 minutes then add the garlic and sauté until fragrant. Remove the veggies from the pan and set aside.
Add pearl couscous to the pan, stirring for a minute so that it toasts lightly. Once toasted, add the chicken broth and let this come to a bubble, then cover fully and simmer for about 8 minutes.
Once the couscous has absorbed the liquid, add back in the sausage and veggies. Stir to combine, adjust seasonings to your liking, then serve with a squeeze of lemon and some fresh herbs!
