Both me and husband are Polish.
Breakfast
Porridge with almond milk fruit and some walnuts or so, scrambled eggs, boiled eggs, Greek yoghurt with berries and almonds, toast with houmous and some vegetables etc., sometimes toast with peanut butter and jam (more husband than me)
Lunch
salad with cheddar/feta/kidney beans/chicken, some rice cakes, crackers or piece sourdough bread
fruit
Husband likes to eat soup or baked beans for lunch, as he does intermittent fasting and doesn't eat until 2PM.
Tea
vegetable soup, stew with buckwheat, once a week spaghetti, roast chicken etc., sometimes we order pizza or noodles
We barely eat Polish food, maybe few times a year, at Christmas or when we visit family. It's not typical diet Polish people eat (there's lots of fried foods, flour which make me bloated and I put on weight) it's my result of trial and error what works for us health and weight-wise.
