We don't eat a huge amount of meat but I'd say we (family of four) generally have chicken thighs, sausages and one other form of meat each once per week.
So in a week's worth of meals we might have chicken and rice one night, sausages and lentils another, and then maybe a beef/pork pasta dish. In between we might have a veggie soup, omelette and salad,, vegetable chilli etc.
We often have a pasta bake with meat as flavour rather than the main thing - so broccoli with pancetta/bacon.
What other successful veggie family classics are people using? I find it hard not to fall back on meat, but whilst one kid will eat literally anything, the other is a bit pickier - not a massive fan of squash, sweet potato, courgette, cauli or aubergine, which is frustrating!! He'll eat some in a meal (and loves green veg), it's just a bit of a harder sell. He's not even a massive fan of potatoes so jacket pots aren't in the rotation!
Any guidance welcome 😃
