I'm not much of a cook but neither am I a complete stranger to the kitchen. I like to prepare sandwiches to take with me to work in a box. Since I do it often, I like to make them more "interesting" than just plain bread-meat-cheese. So far however I've only come up with the idea of putting in various off-the-shelf sauces/dressings/whathaveyou that I can buy in the supermarket.
Whenever I buy and eat pre-made sandwiches, they taste a lot better than what I make myself. I've tried to figure out why this is and I think it's because they contain vegetables. I like vegetables in a sandwich - cucumbers, lettuce, tomato, avocado, bell peppers, etc.
The problem with adding them myself is that it just takes too much time to do. I usually make the sandwiches in a hurry in the morning, so I have about 5-10 minutes to do it. Washing-peeling-slicing-storing - that just takes too much time. Sometimes I add pickles, but most of the time I consider even that too big of a hassle.
So I was thinking - if I could pre-slice the vegetables and store them for several days (ideally - up to 5 days), that would do it. I'd just have to grab them from a box and throw them on the sandwich. I'm afraid however that sliced vegetables won't keep so long, even in the fridge. I haven't tried it though.
Are there any tricks out there that could help me? Some way to make sure they last longer, or perhaps are much quicker to prepare in the mornings? We can skip tomatoes, I think a sandwich with tomatoes in it would be a mess after several hours in a box anyway.
Or perhaps other ideas to quickly give a sandwich an interesting taste? (Subjective, I know, but I'm not picky and will try different things)
