Every few weeks I make a bolognese sause, which requires some upfront time because you really can't make one in under 4 hours. Well you could, but it would be slop, and at that point you might as well buy the crap on the shelf.
I then take it and freeze it in 1 ladle quantities, it freezes very well, and then it is ready to go for a variety of quick dishes. Any sort of pasta or topping on chicken etc. Quantity of sause per serving is of course adjusted for your own preference i.e. drenched vs condiment.
I keep these around :

I find them to be quite good and very fast, but you could of course make your own. Add salad and some bread and you can have dinner ready in about 5 minutes because the gnocchis are pre cooked.
Also, keep panko bread crumbs around because you can use these for chicken and pork after dredging and spices (I also add grated parmigiano) and pan fry the cutlets. Very fast, add a vegetable and potato.
I find twice baked potatoes freeze well after the first baking, so I make up a bunch and freeze them. Then you just pull them out and bake them for 20 minutes.
