Bring a large pot of water to a boil. Then fill a large pitcher with water and ice.
Place 3-4 tomatoes in the pot of boiling water. After about 1 minute, remove them with a strainer or tongs and place them in the pitcher of ice water.
Remove tomatoes from ice water after about a minute. Skin will have separated from the meat of the tomato and will peel right off. Remove all the skin and dice. At this point you may choose to seed the tomatoes or not. Up to you. :) Place diced tomatoes in a new large pot and turn heat to medium-low. Continue with remainder of tomatoes.
Dice onion and add to the pot of tomatoes.
Dice jalapeno, banana and ghost peppers. You may choose to leave the seeds of the peppers in if you like more heat. Removing the pepper seeds removes more heat. Add diced peppers to pot of tomatoes.
Add salt and sugar and let simmer for about 10-15 minutes depending on how crunchy or soft you want your peppers. Transfer to a quart-sized Mason jar and store in the fridge.
