Anyone else do something like this? I made this this morning and couldn't believe how good it tasted.

Three heaped tablespoons of yogurt. I use soya yogurt but any unsweetened, unflavoured yogurt of your choice should do.
One teaspoon, or less, of Marmite. This is a UK yeast extract product. The Oz version, I understand, is Vegemite. Is there a US equivalent?
One heaped tablespoon, or more, of tomato puree. This adds sweetness to balance the saltiness in the Marmite.
Two or three peeled cloves of garlic.
Fresh chili to taste.
Two or three heaped tablespoons of cooked beans. I had cannelli beans to hand but butter beans or black turtle beans would do as well.
A small tin of mackerel in oil. 125 grams including the oil.

All this went into the blender at top speed for about a minute.

This would make a couple of servings as a stand alone soup or starter. I used it as a dressing for a chopped salad. I'll get several servings out of it.
