8 qty - Roma tomatoes <<< OR >>> 4 qty - large regular "globe" tomatoes
X qty - Chili peppers [jalpeno, habanero, banana, etc.]
<<< Note: if time limited, the above items can reluctantly be substituted with 2 cans - Rotel (the spicier the better) and 1 can [14oz] - whole peeled tomatoes) >>>
3-4 qty - Limes (again, can be substituted for lime juice, but that's your call)
1 bundle - fresh cilantro
1 - large red or white onion
garlic salt (substitute for powder if you are watching salt intake)
cumin
all purpose seasoning (optional)

Preparation:
Peel the onion and cut it into chunks. 
Wash the cilantro.
<<< Note: If are using canned items, skip this and head to the "cooking" section. >>>
Wash tomatoes. Blanch them and remove the skins.
Cut the stems off the peppers.

Cooking:
Cut or pull the leaves of the cilantro from the stems and place into a blender; use about half of the bundle for now.
Add remaining vegetables into the blender.
Cut and squirt juice of limes into blender (or from a bottle if you chose to do so).
Add a good amount of garlic salt/powder into the blender.
Add a 1.5 - 3 tsp of cumin into the blender.
Add some all purpose seasoning (if you want).

Blend the contents to the consistency of your choosing.

Take a chip and try it, adding more cilantro, lime juice, garlic salt/powder and/or cumin to taste and reblend.
