I'm veggie too but most things can be adapted. A good stock of herbs, spices, passata, tinned tomatoes, soy sauce and honey is a good start.
Favourites here (just me and dd)
Stir fry (always have sauces in but also I will make my own using soy sauce, spices etc) - serve with noodles, cous cous or rice.
Pasta - with homemade tomato pasta sauce (either just basic Italian herbs and garlic or add spice) or homemade crème fraiche or cream cheese or cheddar cheese sauce
Casserole - root veg, quorn chicken or beef pieces, stock, passata based sauces, gravy. Dead easy done in slow cooker
Stroganoff - quorn beef or mushroom or both, crème fraiche, paprika, garlic, parsley, coriander, black pepper.
Fritatta, omelette or baked eggs for a light tea.
Nothing wrong with 'on toast' occasionally either especially if for some reason you've had a big lunch. Beans, spaghetti, tomatoes (with black pepper yum) or creamed mushrooms (double yum)
Lazy days - freezer to oven jobs (pie, things in breadcrumbs with chips mash or wedges and veg), burgers (kids love making them), hot dogs (occasional treat jazz up with onions, sauerkraut, various sauces)
