This is a sandwich I've been making and loving for the past 5+ years, ever since I had started cooking for myself in undergrad. As a result this is a great sandwich that's super cheap and easy to make, and makes the most out of its limited ingredients. One of the best things about this is how full it makes you feel in the morning. I've had a lot of days where I just have to skip lunch, and this sandwich powers me through with a nice combination of ingredients.
10 minutes to prepare.
I've made this sandwich countless of times, here's a few photos of it recently.
