cooking your own food is probably one of the best things you can do to eat healthy. lots of sites online with quick/easy recipes that taste good.
i use https://www.bbcgoodfood.com quite a bit, it has a ton of great recipes that are simple to try. only downside to it is the categorization of the recipes isn't great, so some won't show up in lists that they should.
it's been invaluable for me trying to vary my diet a bit, even if i don't really focus on eating healthily.
