Frequently Asked Questions about this Easy KOO Three Bean Salad Recipe

Can I use fresh green beans instead of tinned?

Yes – if you prefer fresh green beans (rather than the tin), blanch them until crisp-tender, cool them under cold water and then add them in. This gives a fresher texture.

Is this salad gluten-free and vegetarian?

Yes – it contains beans, vegetables and a simple dressing, so it is vegetarian and naturally gluten-free (just check your brands if you’re strictly avoiding gluten).

How sweet or tangy should the dressing be?

The ratio of 2 Tbsp vinegar to 2 Tbsp brown sugar gives a nice balanced tang-sweet flavour. If you prefer more tang, increase the vinegar slightly; for more sweetness add a little extra brown sugar.

Can I add other vegetables?

Absolutely – you can mix in chopped cucumber, cherry tomatoes, spring onions or even cooked corn kernels for extra colour and texture. Just ensure any added veggie is chopped to similar size for uniformity.

Should I drain the beans for a KOO three bean salad?

Drain the butter beans and green beans to remove excess liquid, but do not drain the baked beans. The sauce from the baked beans adds flavour and helps create the sweet and tangy dressing that makes this salad so delicious.
