I'm looking for some different breakfast items that have more protein so I can stay full longer until closer to lunchtime. My typical breakfast includes some kind of cereal (a whole grain type, not a sugary kind) plus almond milk (regular milk upsets my stomach, and I dislike American soy milk). I'm not a huge fan of baked goods (as delicious as they are) like bagels, muffins, and croissants.
Lately though, I have not had a lot of free time to the grocery store so I have been eating some kind of breakfast sandwich (some combination of sausage, egg, cheese, and a bagel/croissant/English muffin) from my office complex's cafeteria or nearby restaurant. The cost and lack of variety associated with this are also things I would like to avoid.
Ideally, I'd like meat but I do not want to spend the time in the morning in my kitchen to prepare and cook things. I prefer to leave early in the morning to get to work to avoid the traffic. In terms of equipment I have a stove, microwave, and toaster at home. At work I have access to a toaster, a hot plate with a small pot, microwave, and hot filtered water (from the coffee machine). There are some markets close to work that open just as I get in to work so I am not opposed to driving the extra distance in the morning.
What are suggestions of foods I can buy or minimally prepare that will keep me full for a longer time?
