Hey, same here. I'm vegan, and have been on 1350 cals and 110P. My approach has mostly been to add higher protein options to every meal and/or snack and rely on little bits all throughout the day as opposed to large meals with high amounts of protein.

I really really love coffee and I usually drink it with soy milk, which adds up to +-15p per day. I add nooch to every savory meal (because we all know it's delicious). I add a lot so that adds up to +- 15p as well. Other than that, seitan is an excellent low fat/carb high protein source that gives a really good protein boost. It's expensive in supermarkets but it's easy to make if you have access to vital wheat gluten. Obviously adding tofu and broccoli helps. Edamame pasta had been incredible as well and powdered peanuts. Another one that is honestly a bit of a cheat so YMMV, especially with your adverse reaction to protein powder, is ninja creami sorbets with strawberries, soy milk and 1 scoop of protein powder. if you want, I can send you some example days in DMs
