Heat olive oil in a skillet over medium high heat. Add the spinach in batches and season with salt. Sauté until spinach is wilted.
Once spinach is wilted transfer to food processor, and pulse until chopped and smooth.
After all the spinach is sautéed, add the tomatoes through cumin to the hot skillet and sauté for 1-2 minutes; then add the spinach, garbanzo beans, kidney beans, and potatoes; then add the coconut milk and toss to combine.
Once the coconut milk comes to a boil add the sugar or honey and lemon juice. Taste and adjust seasoning.
Meanwhile, in a food processor add the carrots and zucchini and pulse until thick puree.
Drain the meat. While meat is draining, in the same skillet used to brown the meat, add the pureed vegetables and cook for 2-3 minutes. Then add the ketchup through brown sugar and toss to combine. Add the meat back to skillet and toss to combine.
If eating straight from skillet, add 1/4 c. water (or desired amount), taste and adjust seasoning.
If adding to crockpot, add the mixture to the crockpot (don’t add the water), cover and cook on HIGH for 3-4 hours.
For the Chimichurri Sauce, combine all ingredients except olive oil in a food processor and puree until ingredients are combined and fairly well pureed. Leave just a bit of texture.
Transfer to a bowl and add olive oil. Stir until well combined. If too thick, add a bit more olive oil or lemon juice, to taste.
Sauce can be made up to 2 days in advance. Keep refrigerated until ready to use. Bring to room temperature for 30 minutes before serving.
For the meat, combine dried rosemary, garlic powder, salt and pepper in a small bowl. Rub mixture between your fingers to crush the rosemary.
Rub mixture onto beef on both sides and place meat on a dinner plate. Cover loosely and allow to come to room temperature for 30-45 minutes.
Heat grill to medium high.
Clean the grill grate thoroughly with a wire grille brush and wipe it with a paper towel soaked with cooking oil. Do this with a long handled tongs.
Place steaks on the grill and cook for 5-7 minutes per side or until meat reaches 120F (for rare) or 130F (for medium). If meat is deep golden brown on the outside, but has still not reached the desired internal temperature, move meat to indirect heat to finish cooking.
Remove from grill and tent meat with foil. Allow to rest for 5 minutes before serving. (This allows the juices to return to the meat.)
Slice against the grain and serve with Chimichurri Sauce.
