Hi, long time vegan, but rather new to cycling. I used to be OMAD (please don't question the health/fitness, I'm just poor, not ideological), but due to cycling I need to eat 2 meals to have the strength to get back home (riding uphill). I tried eating breakfast, but by the time I get to work and get through the shift, I think anything from breakfast is gone and useless, because I struggle with going uphill. I don't struggle, however, if I eat lunch. But premade lunches are too expensive.

• I live completely alone.
• Buying entire lettuce and even just half a bread is too much for me and a part of it will go bad, making me feel awful (even environmental reasons aside, again, I'm poor, so it hurts more to spend money I don't have much of on things in the end going to waste). No, I don't want to seek ways to eat the exact same thing every single time, it's making me depressed.
• I'm not interested in long preparation time nor cooking for the week. I don't even own stuff I could pack food into, but I of course can buy one container suitable for whatever meal for work you may help me come up with.
• I enjoy the simplicity of putting cereals together via just putting them in a bowl and submerging them in m!lk, to give context for the simplicity I yearn for.

I will deeply appreciate no poor-shaming and being helpful over trying to impose a semblance of moral superiority over having different life ways than myself.

I'm from a poor family, so I don't have experience with breakfasts/lunches at all. I spent my life eating dinner only.

I was thinking of oatmeal with fruit, but I have no idea if it's a good idea...? I've never done oatmeal before. From what I've read, it's done in minutes. But I also fear it will spill. Do lunch containers keep in soup-like food like oatmeal well? What cheap fruit goes well with it? Berries are mad expensive, I was thinking of buying pears, maybe apples, and cinnamon.
