1 glass of pure fruit juice counts.
I also ‘hide’ lots of veg. Put courgette in anything with mince, grated if you don’t like it, can grate in carrot too and not really notice it, finely chopped bell peppers too.
Bit less commonly done, If I’m doing cottage pie and serving with veg, I’ll finely dice broccoli and/or cauliflower stalk the same size as the carrot and peas too, they can be grated as well into any mince. Bulks it out, uses less meat and makes it healthier.
I always add frozen green beans, snapped up if needed, to curry. Fresh cauliflower and bell pepper is good in there too.
Adding frozen or fresh fruit to your breakfast cereal or a yogurt is quite a good one for not really being too much effort, as is 1 glass of pure fruit juice.
