Thanks.
For us, and I think we were probably a bit better cooks than is normal, hamburgers would count as a lazy meal, assuming you mean cooking something like [1] from the fresh meat section.
Hot dogs, eggs alone, or ramen -- no; this is food for when you've arrived home alone drunk at 4:30. Or woken up hungover.
Roast chicken or steak is fine, so long as there's also some vegetables and some kind of sauce.
Average meals would be things like curries or stir-fries made with a pre-prepared sauce or spice mix, chicken/turkey fricassees, risottos, or casseroles. I think we discovered fairly quickly that £3 tetra pak wine improved most dishes, so long as one didn't drink it.
The Blue Apron recipes have fancier ingredients than we would have bought when we were 18-22, and a little more effort in the sauces. Looking at things like [2] and [3], the skill required was well within what we could make, although we'd probably use dried herbs, cheaper vegetables (canned sweetcorn, normal size tomatoes), and normal meat rather than anything special.
In fact, the "Fresh Basil Fettuccine" is almost exactly like our "use up what's left in the fridge" meal.
