Pasta with tomato sauce -- variations: chop sausage (salsiccia, chorizo) into bits and fry and add, add chickpeas, add leafy spinach and stir in. I don't want to eat this ever again, personally. So sick of it.
Chop a chicken into bits (breasts, thighs, drumsticks, wings and back (back isn't eaten, admittedly), season, in oven for 45 minutes on 200 degrees - dinner is done in an hour which is acceptable to me, serve with rice or potatoes, use "stock" from the pan as "sauce" -- this meal is so simple I can do it in my sleep and could personally eat it several days a week but my husband is fussier and "needs variation" apparently

Quick tacos à la Sweden -- fry mince with seasoning (cumin, paprika, garlic and onion powder) and serve with chili sauce, lettuce, thinly sliced red onion, cucumber slices, maybe sweet corn from a tin, maybe avocado or guacamole, maybe sour cream, and tortillas. Everybody builds their own. Difficult for small children.
