I’m not sure how you feel about the dairy industry, but Greek yogurt has been a life saver for me. I didn’t even really like yogurt before this, but it’s very much grown on me. I take chobani fruit on the bottom yogurts to work as breakfast everyday as I get the flats of them at Costco and they are very transportable (110cal, 11g protein) and at home I have fage 2% (120cal, 17g protein) with a splash of vanilla and either some fruit or a little drizzle of honey.
For non-dairy protein lentils are awesome. I like the brown lentils best, the ones you get when you pick up a pack just labeled “lentils.” You can do an easy lentil soup with just chicken broth, sautéed onion, celery, and carrot. Then just toss in a cup of lentils and a bay leaf and let it simmer for an hour. Or dahl is a very easy one pot dish that’s easy to batch cook. I use this recipe https://www.noracooks.com/red-lentil-dahl/ but let it simmer longer with my brown lentils.
For a snack, carrots and hummus is great, just be careful on portion sizes because the fat content in hummus is also high.
I love https://darebee.com/ for all of their free body weight exercises. They have individual workouts and a bunch of programs that you can try. I personally like the programs so it’s less work for me having to pick out my workout everyday, plus some of them have fun rpg storylines.
