I don't aim for 5 portions, I aim for 10 smaller portions as lots of my portions are small.
Breakfast - usually a smoothie made with berries (fresh or frozen), almond butter, seeds and apple juice (the ingredients that count towards this), given that there are often maybe 3-6 types of berries/fruit, I can count it as a few.
Lunch has lots during the week mostly - 2 carrots, half a pepper (sometimes a quarter each of 2 colours!), half an avocado, fistful of lettuce, maybe 5/6 cherry tomatoes and the same of olives, fisftful of sugarsnap peas etc.. that usually counts as 1 portion per veg in the bowl so up to 7 (with a bonus 8th in summer if I have radishes from the garden).
I'll usually manage at least 1 apple or mandarin as a snack from my desk drawer during the day - sometimes a few pieces.
Dinner - can be nothing on bad days, usually at least 1-2 veg, and I try to do things like mixed veg stirfries etc a lot, so there are only small amounts of each but a variety of different veg involved - maybe mushrooms, onion, garlic, peppers, courgette, carrot, broccoli etc. I manage multi-veg options about 3/4 times a week.
The problems are around doing meals that DD can and will eat, in a hurry, at the end of the school/work day that are fast to prepare.
I still do some batch cooking of spag bol sauce and lasagna sauce and cottage pie dinners for the freezer that have lots of veg that are diced up in the food processor (carrots, mushrooms, courgettes, butternut squash etc) along with the onion/garlic/tomato base to the sauce. Cottage pie can have peas visible, as well as my secret ones (less mushroom but often broccoli or cauliflower work well with beef).
