Blocks of tofu stir-fried in a spicy, thick sauce studded with sweet peas is a winter comfort food for me. It clears the sinuses, tickles the tastebuds and it’s wickedly quick to produce. I never thought others would care much for it, knowing that tofu can be a tough sell. But after sharing this dish a few times over the years, many have dug in appreciatively and asked how it was done. It’s criminally easy so here goes.
