Bonus points for healthy/low carb. Omivore, vegetarian, vegan, I eat all the things but my autistic ass is very low on spoons. I'm a good cook but even the thought of cooking instant ramen sounds daunting sometimes.
Easy things I've incorporated are protein shakes with coffee, flax milk and chia seeds during the morning. Keeps me good til 1pm or so since breakfast grosses me out during the weekdays and it takes like 2 minutes to prepare
Also wraps. Throw a protein on, condiments or a sauce like pesto or something, rip up some lettuce with your BARE HANDS, and that's it. Or if you're feeling fancy, slice up some cheese/veggies. Less than 5 minutes with minimal clean up, just a cutting board knife, plate and maybe a spoon or butter knife. Sometimes if I'm not cutting much ill just do it carefully in my hands or on my plate to avoid washing the cutting board
Yeah. Then add the oil later because in my experience, it it gets too cold it'll solidify.
You can add potatoes too if you want to make a potato salad without any mayonnaise. You can always substitute balsamic vinegar with a bit of lemon juice if you feel like it. I did that once with some scraps of leftover boiled potato and it turned out pretty good. Especially with a bit of oregano.
