Request: Something vegetarian tex-mex/mexican to go in tortillas? (ingredients inside)

I'm in the UK and most people buy tortilla seasoning packs and mix it with chicken or ground beef but I want to make something from scratch. Tex mex and actual mexican food aren't as popular here so looking for some good recipes.

Here's what I have in my kitchen that I think could be used, I'll mostly list my condiments and spices/herbs first:

• Sliced jalapenos in a jar (red jar and green jar)
• Dried whole birds eye chilis (think you call these thai chilis in the States - they pack a bit of a punch!)
• Soy sauce & Marmite & Worcestershire Sauce (I sometimes use these to add a bit of a salty/meaty taste to things)
• Ground Cumin
• Ground Cinnamon
• Mustard Seeds
• Thyme
• Oregano
• Sage
• Dried Cayenne Pepper (powder form)
• Habanero Chili Flakes
• Chipotle Chili Grinder
• Chipotle Paste
• Encona West Indian Hot Pepper Sauce (Uses mostly habanaro peppers and some scotch bonnet)
• Cholula Hot Sauce (got both original and the garlic chili version)
• Franks Hot Sauce (not a huge fan, tastes too salty for my tastes)
• A couple of generic Heinz hot sauces (not very hot though), one is habanaro, the other is chipotle and the other is jalapeno
• Chicken stock cubes
• A jar of minced garlic
• Clear honey
• Black Pepper & Salt
• Cheddar cheese
• Bell peppers (red and green)
• Large white onions
• Spring onions
• Tinned (canned) chopped tomatos
• Fresh cherry tomatoes
• Sundried tomatoes in olive oil
• Red kidney beans
• Baked beans (in the UK these are navy beans in a sugary tomato sauce, I could always run the sauce off with water before using them so they're more adaptable)
• Sweetcorn (frozen)
• Cornflour
• and I also have rice and some squeezy guacamole and salsa (normal and a tropical one with mango, pineapple and papaya - both by old el paso)
• Also I have apple cider vinegar, balsamic vinegar and british table vinegar which is brown malt vinegar i think - no limes or lemons for acid unfortunately

I'm comfortable with heat having grown up eating Indian, Pakistani and Bangladeshi food so if any Mexicans want to take that as a challenge and recommend something with a bit of a kick that's good by me! I also have the whole day ahead of me so time is not an issue.

Don't know if it's worth mentioning but I have a frying pan, a griddle pan, some normal pots and pans, a crock pot (slow cooker) and a food processor.

bon appetit
