I often make a breakfast "skillet" thing. This takes about 20 minutes so you'll have to plan around it if you have a commute.

• 1 or 2 potatoes
• 1/2 to 1 onion
• 1/2 bell pepper
• 1 portion seitan, soy chorizo, fake sausage, etc
• a couple mushrooms
• 1/2 avocado
• some fake cheese
• bbq sauce or spices (chili, cumin, paprika, etc)

1. Peel and dice potatoes. Put them in frying pan over medium heat with some oil. These take roughly 20 minutes to cook, the smaller the pieces the faster they cook. Let them get good and brown, enough for them to naturally "release" from the pan, before you start flipping them
2. Add salt and spices
3. Dice the onion, bell peppers, mushrooms, seitan. Add to pan as you go, in the order of what needs to cook the longest.
4. Once the potatoes are fully cooked, add fake cheese and avocado. Once incorporated, turn off the heat and add BBQ sauce, if using.
