In a non-stick dish, heat the olive oil.

Add the finely chopped garlic and sautee for about half a minute.

Next, add the chopped white onion and sautee well.

When the onion just begins to turn translucent, add the brown sugar and mix well to incorporate. leave it on a medium heat, stirring occasionally, till the onions are starting to caramelize.

At this stage, add the sliced sausages and stir well. the sausages will start to release some of their fats and will shrink in size.

Add the can of Ro*Tel (undrained) and mix well. let it come to a boil.

Reduce the heat to a simmer, and season with salt, pepper and ground cumin.

Continue to simmer till the salsa thickens slightly (to the consistency u desire). at this stage, turn off the heat and transfer to a serving dish.

Sprinkle with the grated cheese (if u have access to mexican cheeses like asadero, manchego, etc by all means go ahead and use them!). serve warm.
