These are super simple, take under 20 minutes, and people love them.
For a dinner: Baked salmon with lemon, butter, garlic and dill. Saute some spinach on the side. For a lunch: Sandwich. Crusty baguette, a soft cheese of some sort, slices of green apples. Maybe a cured meat like prosciutto if you are feeling that. Takes no time at all to make but feels fancy. For a breakfast: Oatmeal with guava paste. It turns pink which is fun, then toast some slivered almonds in a bit of butter and server them hot on top.
I got a Sony PRS-505 from late 2007, around the time of the first kindle. At the time it was amazing to be able to travel with just that instead of travel guides and multiple novels like I did before taking up weight and space. That was also like two years prior to me getting a smart phone. Since then I have had two different kindles, but they did not have as much of an impact as that sony ereader did.
