I found this recipe on Naomi's My Paleo Kitchen blog (Naomi appears to be AWOL, her last post was November). It can be found here: http://mypaleokitchen.blogspot.com/...beef-mince.html
I have tweaked some so here is my version:
Beef and Summer Squash Saute
A one pot meal...
1 pound ground beef (organic REALLY does taste, smell and look better)
4 zucchini diced (or mix and match, I usually use 2 zukes and 2 yellow crooknecks)
4 roma tomatoes, chopped (or a can of diced, I like the ones with seasonings)
Onion, chopped (I used 1 large)
Garlic, minced (I used 4-6 cloves)
Seasonings (I used dried oregano and basil, about 1 1/2 tsp each)
Salt and pepper
Brown beef in skillet with chopped onions and minced garlic until meat is browned. Season with spices. Add tomatoes (I add the liquid when using a can as well) and diced squash. Stir well and saute for a few minutes until zucchini is tender. Makes 4 good sized servings.
I love this stuff, having it almost weekly now. Very fast, easy and nutritious. If you do dairy it is nice with some fresh grated Parmesan cheese sprinkled on top.
