Um, if you like bell pepper and onion I can recommend coca de trampó. It's like pizza a lot more oily and takes longer to bake. My bastardized version of the recipe is:

• Chop 2 medium sized bell peppers (red and green or whatever you like), an onion and a medium tomato. You can chop them to strips or squares. Put everything in a bowl.
• Add a bit of oil (should be olive oil but if it's too expensive just use seed oil), enough to soak everything. Add sweet paprika. Add crushed tomato (like a cup or cup and a half, I normally add a whole can which is like 400g).
• Mix that evenly.
• While that macerates, make the dough by adding half a cup of oil and a cup of water.
• Add flour while stirring so as to avoid lumps, until the dough doesn't stick to the bowl.
• Spread the dough in an oven plate (if you have a small oven like me you can make two)
• Put that in the oven for like 10 minutes at 200°C, or until it you see the surface "solidify".
• Take out the plate and spread the vegetables over the base.
• Put everything back in the oven for like 30-40 minutes depending on how hard you like the dough to be.

Hey, it may be oily as hell but it's so fucking good

Unrelated to above: you should also have frozen vegetables in the freezer so that you can cook them quickly whenever you need. Also have cans/jars at hand for the same reason. If you cook something that takes long, go all in and make at least a kilo so you can store for later in the freezer. Get glass tupperware.
