Place a large skillet over medium-high heat. Cook the sausage until no longer pink, about 8 minutes. Drain any excess grease.
Stir in the Rotel tomatoes. Add the Velveeta and stir until creamy and melted.
Top with sliced green onions and diced tomatoes for garnish. Serve warm with tortilla chips for dipping.
Notes
If you'd like to add cheddar cheese on top be sure to use an oven-safe skillet or transfer the dip to a baking dish. Then sprinkle shredded cheddar cheese over the finished dip. Then place the skillet under your oven's broiler until the cheddar is melted.
