Lots of variations on meat/fish and two veg: pan fry lamb chops, pork chops, escalopes, steaks, chicken. Or a fillet/steak of any fish. Eat with salad/green beans/new potatoes/courgettes etc. Very quick as long as you time it right (eg put the new potatoes on first as they take longest to cook and do everything else while they cook).
Cous cous and halloumi: Chop and fry together tomatoes, garlic and red pepper. Cook cous cous by pouring over boiling water and covering for 5 min. Stir together. Slice and fry halloumi.
Tricolore salad - chopped mozzarella, avocado, tomatoes, basil.
Substantial salad - cook new potatoes and lardons and mix with salad leaves. Also add avocado, cheese and/or nuts if you fancy them
Duck breast salad - cook duck breast, slice up, serve with salad leaves and bread. Extravagant but delicious. Same for steak.
To add to all the pasta ideas:
Gnocchi with blue cheese sauce - melt blue cheese and cream together, add spinach till it wilts, cook gnocchi (2 min) and stir together
Fresh pasta with mushroom and cream sauce: fry mushrooms with bit of garlic, add cream and parsley, stir into cooked fresh pasta.
