Heat the oil in a Dutch oven over medium heat. Add onion, garlic, and Sauté for 2 minutes until softened.
Stir in the potatoes, bell peppers, zucchini and season with salt, pepper, paprika, and Italian seasoning. Cook for another 3–4 minutes, stirring occasionally.
Pour in the crushed tomatoes mix to combine. Bring to a simmer, then reduce heat to low. Cover and cook for 20–25 minutes, or until the potatoes are tender.
Taste and adjust seasoning before serving. Serve hot.
Notes
Consistency: The crushed tomatoes provide enough liquid for a thick stew. If you prefer it more soupy, add ½–1 cup vegetable broth or water.
Garlic: if you aren't a fan of garlic, feel free to leave out the garlic powder.
Seasoning swap: You can replace Italian seasoning with ½ teaspoon coriander.
Make it heartier: Stir in a can of chickpeas, kidney beans, or lentils for extra protein.
Storage: Cool completely, then refrigerate in an airtight container for up to 4 days. Freeze for up to 2 months. Thaw overnight in the fridge before reheating. The texture of vegetables may change and soften slightly, but the stew will still taste delicious.
