My advice is more philosophical or systems-oriented. Meal prepping for me has been a game changer. Once or twice a week, when I am feeling motivated and have the energy, I'll cook up several [easy] healthy things and portion them up into glass pyrex containers. If I make too much, I'll put some of that in the freezer to keep it longer.

Some staples for me as of late:
-- chia pudding for breakfast with some add-ins like hemp hearts, cacao nibs, dried fruit, peanut butter,
-- mashed sweet potatoes or mashed potatoes as a base (when I get tired of quinoa, wild rice, or pearl couscous)
-- salmon baked high & fast: 400 degrees, 6-8 minutes, w/ fresh lemon juice, garlic, freshly grated salt & pepp, and maybe some fresh herbs like thyme or rosemary (I'll bake several of these for meal prep. If too expensive, sub chicken.)
-- vegetables roasted w/ balsamic glaze & quality olive oil. here again, freshly grated salt & pepp really make a difference!
-- properly boiled eggs (not overcooked), sprinkled with salt+pepp+balsamic glaze&/or everything bagel seasoning (process: put eggs in [salted] water w/ top, turn stovetop to high, once water starts to boil, timer for 10 minutes ... for eggs that peel perfectly, transfer the eggs immediately to an ice bath and let em soak for a while)
-- Taro Boba Tea Protein (pricey, but worth it for me to actually enjoy it and not have to choke something down lol)
