My "I'm tired but need veggies" go-tos:

Keeping a container of celery sticks and baby carrots in the fridge, and optionally bit of dip. (Greek yoghurt, garlic powder, salt, and lemon can be a nice easy dip)

Cucumber salad with white vinegar, soy sauce, and sesame oil. Also add green onion or onion powder and chili pepper flakes for more flavour

Yóu cài, the Chinese green, stir fried with garlic, cooking oil, and soy sauce. Drizzle with sesame oil and serve with rice and a fried egg.

Boiled cut broccoli with salt, garlic, and a bit of oil, trying to not overcook. Personally I find it always tastes better than I think it will

Stir frying broccoli, carrots (sliced or precut matchstick), and optional shredded cabbage (can also be bought pre-shredded) with onions and ginger in cooking oil. Add teriyaki sauce, or soy with hoisin sauce.

Chopped bell peppers.

Additional tip if you struggle with preparing veggies for dinner: I buy the no name pre roasted garlic paste, and ginger paste and keep them in the fridge. Yes it costs something to have it already prepared, but it reduces enough effort and enough complaints from others about cooking smell enough to minimize my chances of eating out, which very quickly makes up much more than the cost of the prepared seasonings.

Zucchini fried in butter.

Boiled carrots topped with butter or margarine.

Another random tip: supplements can be expensive, but if you want to try them without dropping a ton of money Dollarama sells Majieson Multi vitamins for I think $4.50 CAD for 20 caplets (1 per day)

Additional product tip: some Chinese grocery stores sell tofu/soy-based skewers, pre-packaged in chili oil. I sometimes have this with the yóu cài mentioned a few lines ago, or other greens like pea tips or Chinese broccoli

Coffee tip: if you keep buying coffee or tea because you are a night owl and very much not an early bird, prepare ice coffee or tea the night before

Kimchi + rice and optional fresh veggies like lettuce or bell peppers if I want a less intense flavour all the way through

Rinsed can of kidney or romano beans + Rapini + garlic + olive oil, cooked on low-medium in a saucepan for Italian veggies

Mushrooms + onion + bell peppers + salt and pepper in olive or cooking oil, in a saucepan on medium-high or BBQ'd

For if you are constipated: Okra + garlic and salt + cooking oil, cooked on low until a much more yellow/brown than bright green for very high fibre. Note, if you eat a lot of this it really will make you need to poop a lot for a while

Broth of onions, salt, pepper, and a bit of rosemary and thyme, with white miso paste. Add kale and carrots or whatever other veggies you want

Basically any veggies + premade taco seasoning. (Eg. Cabbage, cauliflower, broccoli, can of rinsed beans)

Tip: want to cook some fresh garlic in your food but don't have the energy to prepare as much as you'd like? Try preparing one or two cloves then adding garlic powder for the rest. Doesn't have to be all or nothing.
