One of my favourite snacks is baked tofu strips.
Take a block of firm tofu and cut it into long, flat strips then brush the strips on both sides with the sauce of your choice (soy, teriyaki, sweet and sour… anything), lay them on a paper lined sheet and bake at about 175°C. The baking time varies enormously depending on how thick you slice the tofu but especially on the sauce you use (soy takes about 25 minutes, teriyaki takes half that), just check them every few minutes and turn when the tops look dry and are starting to brown, then let them go for a bit less on the other side. They come out kind of chewy and delicious.
As a snack or appetiser, you can serve them with a dipping sauce of your choice. One of my favourites is peanut.
2 heaped tablespoons of smooth peanut butter
2 tablespoons of soy sauce
1 teaspoon of rice vinegar
1 crushed clove of garlic
half a teaspoon of ground ginger
a teaspoon of chilli flakes
a few drops of sesame oil
about 1/3 of a cup of water
Mix well together in a small pan over a low heat until thick.
The tofu strips also go really well piled on top of a veggie stirfry and a pile of noodles.
