To make the salsa, dice the tomato into small pieces. Make sure you remove the seeds and wet pulp before dicing. Mince the yellow onion and pickled jalapeno (you may use raw jalapeno as well). Combine these ingredients with lime juice, salt, and minced cilantro. Make sure the first three ingredients are diced or minced small enough so you’ll be able to pick up the salsa with your tortilla chips.
To make the tortilla chips, turn on the oven to preheat to 375 degrees. Line a sheet tray with parchment paper, and slice each cheese slice into 4 triangles. Arrange the triangles on the parchment paper, and bake the tortilla chips in your oven for 9-10 minutes. Watch for the cheese triangles to melt, bubble, and harden into dark orange chips. Look for firm orange centers and browned edges on the chips to know they’re done.
Wait for the tortilla chips to cool completely before lifting from the parchment paper and serving with your salsa. Adjust your salsa to taste with the ingredients you’ve used. At your discretion, you may also choose to make your salsa in advance to marinate overnight in your refrigerator. This will blend the flavors and tenderize the ingredients more.
