Bubbling hot and cheesy, this dip makes a generous amount of delicious appetizer served with tortilla chips, crackers, or toast points. With the addition of a side salad, it will serve as a meal for two - four. The recipe is very forgiving of variation! Vary the quantities of mayo or cheese. Adjust the spices to suit you. Leave out the diced fresh veggies or use prepared "veggie cream cheese" to cut down on prep time. Substitute crab or salmon if you're not a tuna lover.
