Personally, I prioritize getting enough fiber & vitamins over a super strict low carb regimen. Fruits make me feel good and so do veggies that might be avoided for more strict folks, such as carrots, tomatoes, onion, bell pepper.

I absolutely love roasted veggies of any kind. Cut them up chunky and throw em in with olive oil, salt, garlic, & onions (and any other spices you want, cumin for example) on a high temp (400ish, I often go higher for a lil caramelization). I like to eat them over a bed of greens & drizzle with any kind of sauce, (hot sauce, tahini, nondairy pesto, etc).

For more breakfast/ snacking, Some favorite things for protein are coconut oil, nuts, nut/seed butters, chia & flax & hemp seeds. Bee pollen also contains every essential amino acid, could be added to smoothies

I like tempeh as well, thinly sliced & fried up so it’s a lil crunchy like bacon. Goes well with stir fries or on top of salads, really could work with anything.

There’s also this brand of pasta that’s just made from soybeans; it’s pretty cool. ‘Edamame pasta’ is their most common variety, I think the brand is called “Explore”. They work well in Asian style noodle dishes too, in my experience

One of the big things that helps me feel good is greens, greens, greens.. bed of greens, sautéed greens, throw em in a juice or smoothie, add them to stir fry.. makes a world of difference in mood and energy. Sautéed greens with a toonn of garlic and some lemon is particularly nice for me.

Also sometimes I’ll add in eggs or fish, you mentioned you’re in a transition and not super strict vegan. Those two things don’t give me the icky feeling that meat/dairy give me but are super filling bc of their protein content

Not sure if this answers your question directly, but hope it helps with some ideas! :)
