In a large saute pan, cook ground beef over medium heat until cooked through, about 5-6 minutes. Drain any excess liquid/fat. Add minced garlic, shallots, and chopped poblano, cooking another 5 minutes until pepper has softened. Stir often so the garlic doesn't burn.
Add salt, if desired, and strained tomatoes, coconut aminos, mustard, vinegar, and paprika along with 1/3 cup of water.
Bring to a simmer and allow it to simmer for 10 minutes, until the sauce has thickened. If it starts getting too thick, just add a little more water.
Notes
If you're sensitive to spicy food, consider cutting back on the amount of poblano pepper. Some are more spicy than others, but overall this pepper is very mild so 1/2 cup should yield a very light heat without burning your mouth. This can also be subbed with green bell pepper.
I used Pomi brand strained tomatoes. These are just pureed tomatoes, like a thick tomato sauce with nothing added.
If sensitive to sodium, adjust the amount of salt and check your coconut aminos for one that's lower.
