Dice the onion, jalapeño, and cherry tomatoes. Mince the garlic. Cube the Velveeta. Measure everything else so it’s ready to go.
In a large skillet or saucepan, melt the 2 tablespoons butterover medium heat. Add the ½ medium onion and sauté for 2–3 minutes until it starts to soften. Stir in the 2 cloves garlic and 1 medium jalapeño and cook for 1 more minute until fragrant.
Stir in 4 oz canned chopped green chiles and ¾ cup cherry tomatoes. Let everything cook together for 2–3 minutes to soften and blend the flavors.
Reduce heat to low. Add the 16 ounces Velveeta cheese and ½ cup milk. Stir frequently until the cheese is melted and smooth.
Once smooth and creamy, stir in the 2 tablespoons chopped cilantro. Taste and adjust with salt or more jalapeño if desired.
Pour into a serving bowl and top with more cilantro or chopped jalapeños if you want extra heat. Serve with tortilla chips, veggies, or drizzle over nachos.
2 tablespoons chopped cilantro
