It is definitely possible to have very little or no processed food and to not feel hard done by
. We buy a few things like oat crackers, pasta, pita bread, ketchup, oh and hummus (since I have yet to make any that the kids will touch!) , but apart from that we pretty much cook everything from scratch. We use the Anna Jones books a lot, and we are gluten free, so don't buy shop bought bread or cereals etc.
Breakfast - Porridge (cooked in the slow cooker with a timer switch so it cooks from 4am...game changer!) with fruit. Or overnight oats (with seeds, nuts, fruit etc).
Lunch - eggs, salad, sauerkraut, carrots, hummus, oat crackers, fish, fruit etc (we tend to do a platter of whatever we have got in the house, so it is slightly different each day and doesn't require any brain space!)
Dinner - we use lots of lentils, chickpeas etc. Tomato based sauces are quick and easy. I LOVE the recipes from the Anna Jones books and we do a lot of bulk cooking to save time. This week we've had lentil ragu, vegetarian curry, falafel, roast chicken, then the next evening a Thai chicken curry (I make stock from the chicken and use as a base in dished during the week). Regular meals are risotto, paella, vegetarian chilli, jacket potatoes with an assortment of side dishes, fish pie, courguette fritters, homemade pizza etc.
Snacks would be hard boiled eggs, oat crackers with almond butter and banana.
I make things like sauerkraut (very simple), yoghurt and kefir as these are great for gut health and very cheap and easy.
Baking - I don't bake very often as it's not my forte, but I make a few things like chocolate cookies (made with black beans, maple syrup, dark chocolate, dates, coconut oil and hazelnuts - again, an Anna Jones one), or banana muffins made with almond flour. We also make waffles using coconut and almond flour, bananas, chia seeds and milk.
We have found that since eating this way we genuinely enjoy our food and fancy processed food less. But we are not militant about it and all love a bag of crisps as much as the next person
. I would say, just introduce a few different meals into your repetoire first, and gradually build up.
