A warming, naturally sweet soup that’s whizzed until silky smooth. Make a double batch — it reheats beautifully for lunches during the week.

2. one-pot vegetable spaghetti – 321 calories per portion

How to make it:
1. Add spaghetti, chopped vegetables (bell pepper, zucchini, cherry tomatoes), vegetable stock, and a splash of olive oil to one large pot.
2. Bring to a boil, then simmer for 10-12 minutes, stirring occasionally, until the pasta is cooked and the liquid has reduced into a light sauce.
3. Season with salt, pepper, and fresh basil, then serve immediately.
