Preheat the waffle iron while you make the waffles.

Grate the potatoes. Place them in a cheesecloth or mesh soup bag and squeeze out as much liquid as possible. Transfer to a bowl and mix in the margarine and salt.

Grease the waffle maker really well with oil spray. Add some potato mixture and cook until golden on both sides. Repeat until all potato mixture is used. Set waffles aside or keep warm in a 200-degree-Fahrenheit oven until ready to serve.

In a large pot, heat oil over medium-high heat for two minutes. Add onions and cook five minutes, stirring occasionally.

Add ground beef, breaking it apart with a wooden spoon. Cook six to seven minutes, until browned, stirring occasionally.

Add chili powder, cumin, sugar, tomato paste, garlic powder, salt, and pepper. Stir until well combined.

Add broth, beans, diced tomatoes (with their juice), and tomato sauce. Stir well.

Bring to a low boil, then reduce heat to low/medium-low and simmer gently, uncovered, for 20 to 25 minutes, stirring occasionally. Remove from the heat and let rest five to 10 minutes before serving.

Prepare pico de gallo: In a bowl, mix tomatoes, onions, jalapeño, lime juice, salt, and cilantro.

Prepare guacamole: In a bowl, mix avocado, mayonnaise, garlic powder, salt, and pepper.

Top latke waffles with chili, pico de gallo, and guacamole.
