i don't know about balanced meal but here is a selection of meals i have made over the past few weeks plus one or two others that popped into my head. we seem to be going through a phase of not using potatoes.
Baba ghanoush, falafel, cous cous in pitta bread with melon for pudding (we?re out of salad to serve it with)
Green lentils cooked with garam masala, coriander, ginger and garlic, dressed with lemon juice, balsamic vinegar and olive oil. Served with asparagus, rocket/watercress/spinach salad (found it in the reduced section) and green beans. Not all veg in one day, meal was split over two days.
Chippy 
Load of veggies stir fried (onion, pepper, carrot, mushrooms, broccoli, frozen spinach, frozen peas, frozed sweetcorn, courgette, garlic tinned pineapple) tin of beans (i used borlotti) with spices (eg. Discovery spices or make your own), added tomato puree and lemon juice. Served with wraps and salsa (home-made of jar ? in past years when we had a garden i was to batch freeze cooked tomatoes from the garden). [2 days] If you like chicken then coating it in flour that has been mixed with paprika, lemon juice, salt and pepper is a good addition. If having guests then pre-making salsa and guacamole as well.
Caponata with quinoa in pitta breads (sometimes DH has this with sausage and coucous instead) [2 days]
Penne pasta, pan fried fresh spinach and toasted pinenuts. I like this meal as it is all cooked in the time it takes to cook the pasta, so quick, simple and healthy.
Home-made bean burgers, with home-made potato wedges and veg. (I generally do half the wedges with garam masala and chilli and the other half with paprika, all with salt and pepper). Obviously can do with mash as well.
Once i need to go shopping then a red lentil or yellow pea dall is handy. Can cook just with spices or if other veggies are around like squash, carrots beetroot. Served with rice and a frozen veg.
Veggie Chilli with pinto beans
Lentil shepards pie, good once winter comes around again.
A hot green salad. Something we do if we have a fair few green veggies. Stir fry veggies, add a tin of beans. Boil some potatoes and mix. Dress with a French mustard, red wine vinegar, olive oil dressing.
Sometimes I do make warm hoummus with potato wedges and veg.
