Spaghetti with bacon and brussel sprouts

Tonight I felt like skipping the gluten and dairy free diet and make something that's one of my favourite midweek meals. It's a really simple dish and even though it does contain both milk, flour and pasta it's quite healty.

Spaghetti with bacon and brussel sprouts
250 g wholegrain spaghetti
200 g diced bacon
1 shallot (I used two since I like onions)
400 g brussel sprouts
1 tbsp flour
2 dl milk
Pepper
Tomatoes

Clean the brussel sprouts and boil them for about 10-15 minutes. Boil the spaghetti according to the timeline stated on the package. Chop the onion and fry them together with the bacon on medium heat until the bacon is a bit crispy. Sprinkle the flour and add the milk. Let it simmer for a couple of minutes.
Cut the cooked brussel sprouts in halfs and add them to the pan. Season with some pepper and mix together. Serve with pasta and tomato.
