Keeping It Fresh
- Fridge: Store in airtight containers for 4–5 days. Flavor deepens by day two.

- Reheat: Warm on the stove over medium or microwave in short bursts.
Add a splash of broth if it thickens.

- Fiber-rich veggies: Cabbage, broccoli, and zucchini support digestion and steady energy.
- Antioxidants: Tomatoes, peppers, and herbs bring vitamins A and C.
- Balanced seasonings: Lemon and herbs cut the need for extra salt.
Pitfalls to Watch Out For
- Overcooking: Zucchini and broccoli can go mushy. Stick to the time guide.
- Too salty: Use low-sodium broth and season to taste at the end.
- Flat flavor: Don’t skip lemon. Acid wakes up the whole pot.
- Veggies cut too small: Aim for 1/2–3/4 inch pieces so they hold texture.

Can I make this on the stovetop instead?
Yes. Sauté onion and garlic in a large pot, add the remaining ingredients, bring to a simmer, then cook over low heat for 30–40 minutes until veggies are tender.
How do I add more protein without changing the flavor?
Stir in a can of rinsed chickpeas or white beans near the end, or add cooked shredded chicken or turkey. Keep seasonings the same and add a bit more lemon at the end.
What if I don’t like cabbage?
Use kale, spinach, or finely chopped Swiss chard.
Add tender greens in the last 10 minutes so they stay bright.
Can I use frozen vegetables?
Absolutely. Add sturdy frozen veggies (carrots, broccoli, peppers) at the start, and tender ones (peas, spinach) in the last 10 minutes.
How can I make it more filling?
Add beans, quinoa (pre-cooked), or small pasta at the end. You can also serve with crusty bread or a simple side like this fresh Strawberry Walnut Spring Salad.
