Heat olive oil in a large pot over medium heat.

Add the diced onion and sauté until softened, about 3–4 minutes.

Stir in garlic and ginger; cook for another 1–2 minutes until fragrant.

Add the bell peppers, Italian seasoning, red pepper flakes, and sea salt. Cook for 2–3 minutes, stirring occasionally.

Pour in the broth (if using) and bring the mixture to a gentle simmer.

Add any additional vegetables and cook until tender, about 5–7 minutes.

Taste and adjust seasoning as needed.
