FAQs
Can I use fresh green beans instead of canned?
Yes, fresh green beans can be used. Blanch them in boiling water for a few minutes until tender-crisp, then drain and cool before mixing with the other ingredients.
Is there a dairy-free alternative for the cream of mushroom soup?
Absolutely. You can use a dairy-free cream of mushroom soup or make a homemade version using vegetable broth and a plant-based milk thickened with flour or cornstarch.
