One of my favorite cook books is "Appetite for Reduction" which is a vegan low calorie cookbook.
The recipes are delicious and really helped a super non-vegan like myself give more veggies a try!
For those interested in healthy, low-fat and delicious vegan meals, I cannot more highly recommend Isa Chanda Moskowitz's recipe book, Appetite for Reduction. It provides nutritional breakdowns for each recipe, the serving sizes are wonderfully filling, and a serving of each recipe rarely breaks the 400kcal threshold.
I've been using that book exclusively to cook meals over the past month, and along with a rigorous exercise regimen it has been instrumental in helping me to lose 20 pounds so far--and all without feeling underfed or like I'm eating tasteless foods.
Here are some websites I like!
https://runningonrealfood.com (all vegan, mostly oil-free)
https://minimalistbaker.com/ (not exclusively vegetarian/vegan, but mostly, some good oil-free and low-oil options)
https://monkeyandmekitchenadventures.com/ (all whole foods plant based, so all vegan and oil-free)
And I like the cookbook book Appetite for Reduction a lot! All vegan, not oil-free but low oil (most recipes call for a teaspoon) and low calorie.
Here’s a diet vegan cookbook that I love.

There are a lot of things I wouldn't like if I didn't learn any recipes. You might want to get some good cook books:
Appetite For Reduction - don't be thrown by the title, the recipes are tasty, varied, and easy, why I have the book, I don't care that they are lower in calories
There are also many more legumes to try like lentils, mung beans etc.
There is also edamame, tofu, tempeh, seitan

I cook vegan, so this is my jam: Appetite for Reduction. Some recipes can be pantry-heavy, but they're flexible.
I recommend that you get yourself a good cookbook that appeals to you and work through it. The nice thing about working with one book is that the author usually sticks with the same kinds of flavoring agents and tools so you don't have to buy a ton of different things.
For the last few months I have been cooking from Appetite for Reduction because all the recipes are vegetable heavy and very quick to prepare and now I don't even need to make a list when I go to the store I know exactly what I need, lemons, limes, garlic, onions, broccoli, mixed greens, dark leafy greens, cashews, tomatoes, peppers, mushrooms, potatoes, cilantro, whatever fruits and veggies are fresh and on sale, hot sauce different beans, olive oil, almond milk, rice, pasta, quinoa, tempeh, tofu, peanut butter, and coffee.
Sine my spice rack is full and I grow lots of herbs I can make all kinds of things
I think the trick to being able to make lots of different things is to not use any processed foods. To make fast but healthy meals it is easiest to do batch cooking on one day of grains and proteins and then just assemble quick meals out of whole grains, protein, vegetables, and a sauce.
