Whatever you have at home is better than “low sodium organic from the can vegetable stock”.
basic:
1 really big carrot
1 really big onion
2 celery sticks
2 cloves of garlic
1tbsp olive oil
salt
pepper
1 bay leave
1,5 l water
optional:
Just add whatever vegetables you have in the fridge (pepper, chayote, asparagus…)
If I have at home I always add some fresh thyme, cause I like the taste.
Put everything in a same pot. Cook, after boiling, for 30 min. Strain.
