In a medium saucepan, melt the 2 tablespoons of salted butter over medium heat. Once melted, add the 1 tablespoon of diced jalapeños and sauté for about 2 minutes until fragrant. Then, add one of the diced Roma tomatoes and cook for another 2-3 minutes until softened.
Sprinkle the 2 tablespoons of all-purpose flour over the sautéed vegetables and stir well to combine. Allow to cook for about 1 minute to eliminate the raw flour taste.
Slowly pour in the 2 cups of canned unsweetened coconut milk, whisking continuously to avoid lumps. Bring to a gentle simmer, stirring often, until it thickens slightly.
Once thickened, stir in the 1 ounce of taco seasoning and mix well. Gradually add the 8 ounces of shredded Mexican blend cheese, stirring until completely melted and smooth.
Remove from heat and stir in the remaining diced Roma tomato and ½ cup chopped fresh cilantro. Finally, fold in ½ cup of plain Greek yogurt for creaminess and a tangy kick.
Transfer your Healthy Queso to a serving bowl and serve warm with tortilla chips. Enjoy!
