I am a vegan, at least relatively speaking.
This is not as awkward or as culinarily dull as people often imagine.
Here are some recipes I've developed since I've been cooking only vegan food.

 

Seed Snacks

Mix roughly equal parts of sesame seeds, sunflower seeds and gram flour with a little sodium bicarbonate, some salt and whatever spices you like (a little garam masala, say). Add water slowly to make a kind of soft batter. The thinner the mixture (and the shapes you make with it), the crispier the snacks. Heat at least a quarter-inch of oil in a pan and drop spoonfuls of the mixture into it, whatever size and shapes you want. They should fry very quickly. Once golden-brown, remove from the oil and drain. Make several batches.

The same kind of batter can be used to coat vegetables - peppers are fantastic deep fried in gram batter - or to make fritters, with sweetcorn and/or grated potato.

 

Baked Bean Curry

Ingredients:

1 Tin of Baked Beans
Crushed cumin, coriander seeds, and chilli, to taste (around 1 tsp, 1 tsp, 1/2 tsp, say)
Whatever other spices you like
Chopped garlic and ginger, to taste
1 Tbs oil (say)
Some porridge oats or oatmeal
Mushrooms
Extra tomato puree/passata

Method:

Heat the oil in a pan.  When it is pretty hot add the spices and fry for about thirty seconds.  Then add the mushrooms, garlic and ginger and fry for long enough to soften the mushrooms.
Then add the baked beans, then the oats and any extra tomato stuff or whatever else you feel like.  Simmer for a while.
Then serve with rice, or toast or whatever.  Makes one really big serving, or a couple of not-so-big ones, or more if you add more stuff - the oats can add quite a bit of bulk without having too much effect on the flavour, so use more if you're cooking for more than one.

It's worth experimenting with this recipe - a variety of vegetables can work pretty well as can sesame seeds, sunflower seeds, nuts tempeh and tofu. The dish is much tastier than it sounds, and not as baked-beany as you might expect if it's done right.

 

Fried Rice

Ingredients:

Rice
Oil
Ginger
Garlic
Chilli pepper
Cumin
Coriander
Vegetables, etc. (eg. sweetcorn and red pepper)

Method:

Boil the rice. When it's nearly done heat some oil in a wok or similar. When the oil is hot and the rice is ready, add the cumin, coriander and chillis and any other spices or seeds to the oil, then about thirty seconds later add the rice and the ginger and garlic. Fry for a bit. Then add the vegetables, in smallish bits, and fry a little while longer. Serve with soy sauce.

Experiment with different vegetables, other spices (turmeric, black pepper and mustard seeds are all good) and seeds, nuts (cashews, peanuts*), and soya products.

 

Porridge

Porridge is actually great. If you don't believe me that's probably because you've never tried it with maple syrup or pear juice concentrate and hazelnut oil or toasted sesame oil. Or with added cinnamon, muesli, toasted sesame seeds, chopped hazelnuts, dark brown sugar, malt syrup and/or some jam.

 

Ugly Soup 

Ingredients:

Oat Milk (or oats and water)
Spinach
Tomato puree
Ginger
Garlic
Lemon juice
Miso
Pepper
Coriander seeds
Basil

Method:

Add all the ingredients to a bowl or pan, to taste. Heat.
Delicious! But terribly, terribly ugly.

of course, if you prefer, you could always try developing the basic ingredients into a non-ugly form .
