Prepare the vegetables.
In a large pot, heat olive/neutral oil. Once heated, put in your ground beef (or protein of choice) and cook until lightly browned.
Add in the vegetables and mix (if you are including spinach or broccoli, I recommend adding those at the end).
Add water according to the curry roux box instructions (usually about 5.5 cups). It should just cover all the ingredients in the pot.
Bring to a boil and then reduce to a simmer. Simmer for 15 minutes. Make sure to skim off any impurities that bubble up. (If you are adding in spinach and broccoli, I add them in the last 3-5 minutes before the 15 minutes are up.)
Remove from heat and break off the curry blocks and place into the pot. Mix very well. The stew should thicken fairly quickly.
If it is still a bit thin, simmer for 5 more minutes, uncovered.
If you want to blend your ingredients, this is the time to do it.
Serve over rice and enjoy!
