Finely chop vegetables and bacon so they are all about the same size.
Heat a little butter or olive oil in a frying pan on low-medium heat, and lightly fry vegetables and bacon until vegetables soften and bacon starts to crisp.
Meanwhile, prepare couscous according to packet instructions (usually just add hot water and let sit for a few minutes).
Once vegetables and bacon are ready, add sesame oil and mix through.
Remove from heat and mix vegetables, bacon and couscous together in a bowl.
Leave to cool for a few minutes and serve.
